I have an invisible disability, and that comes with social challenges in addition to the ones that come with the disability itself.
In my case, it’s Chronic Fatigue Syndrome (CFS/ME). I have lived with it since my teens, although it got much worse some years ago.
WHEN IS IT INVISIBLE?
In what sense is it invisible?
It’s “invisible” to you if…
You didn’t know me from before I got it, or only from when I functioned better (my twenties and early thirties.)
You only see me on good days and after days of rest. (That’s almost everyone.)
You see me during short periods when I am able to mobilize and exert myself, often more than I should.
You don’t see me when I crash. You don’t see the consequences of mobilizing and doing more than I should, which often are severe and can last days or weeks and sometimes even longer. (Very few do, and those who do are often shocked.)
You have relatively brief interactions with me. (My ability to engage tends to fade relatively fast.)
You have seen in me in groups. (In groups, I tend to leave the active engagement and talking to others so I can rest.)
WHEN IT’S NOT INVISIBLE
To me, it’s certainly not invisible.
I have lived with it for a long time. My life has been dramatically changed because of it. Many if not most of my dreams and plans for this life had to be abandoned.
In daily life, I notice it by the fatigue, the few minutes each day when I am able to do something, poor memory, poor ability to read or take in information, all the strategies I need to use to try to compensate for this, and so on.
To those close to me, it’s also not invisible. They see the rest required before and after any activity, and how brief the periods of activity are. Even those close to me don’t always realize how serious it is. As others, they sometimes think I can function better than I do, or attribute what’s clearly (to me) caused by the illness to personality. This is one of the more painful aspects of the disease. (I had a recent statement from my doctor about my illness, and people close to me seemed a bit shocked when they read it.)
WE FILL IN THE GAPS WITH WHAT WE (THINK WE) KNOW
What’s so difficult with an invisible disability? What’s the extra layer of difficulty beyond the challenges that come with the disability itself?
It’s mainly that others fill in the gaps with what they think they know.
They see me for a few minutes on a good day and after days of rest, so I may appear to function relatively normally. Based on that, they assume that’s how I am the rest of the time.
If they don’t see me or hear from me for a while (weeks, months, years), they assume I am busy with something else. In reality, I am often wiped out and in bed and don’t have the resources to do much beyond the essentials to get through a day.
They attribute what they see to personality. By nature, I am at the high end when it comes to ambition and activity levels. During my twenties, when my health was better, I would fit in several lives into one. (University studies, art, meditation, reading, photography, etc.) These days, I can’t do much apart from resting, so some may assume it reflects my personality and don’t realize it’s because of the disability.
They notice some of the strategies I use to appear to function more normally, and attribute that also to personality. For instance, they may see me quiet in groups and assume it has to do with being shy and that I function better than I do.
In the case of CFS, the label itself can be misleading. It can sound like a lasting tiredness, which is a minor part of a much more serious, complex, and debilitating disability.
FUNDAMENTAL ATTRIBUTION ERROR
I notice the fundamental attribution error frequently when it comes to my own invisible (to some others) disability.
The fundamental attribution error is when we see a certain behavior, and think it’s about the person and not the situation and circumstances.
Of course, some does belong to the person. We are all responsible for how we relate to life, and there are some differences in how we do just that. At the same time, a lot of our behavior can be explained by our situation, circumstances, and our history and the culture we grew up in.
I notice that relatively often. People don’t know me, or don’t me well, or don’t see me flat 95% of the day or in a crash. They see a certain behavior. Maybe that I don’t talk much, or need to rest, or am not very physically active. Or even that there is fear coming up, or that I am grumpy. They attribute that to me and how I am.
They don’t know the bigger picture of the illness and it’s symptoms. The fear that comes up when you can’t function well and risk getting permanently worse through activity. How society and people don’t understand and often don’t meet you with much understanding. And so on.
If they knew, the resting would make sense. The anxiety (survival fear) that comes up in some situations makes sense. The occasional grumpiness (when my system is crashing) makes sense.
HOW TO COMMUNICATE THE SERIOUSNESS OF INVISIBLE DISABILITIES
So how can we communicate the seriousness of invisible disabilities?
One is to use the term and get it out there. The term itself invites some curiosity and, hopefully, a realization that some serious disabilities can be invisible to the casual observer.
I tend to say I have a disability without explaining more, unless they ask. That gets the point home since people know, more or less, what a disability is, but may not be familiar with CFS and how serious it is. I used to say “I have CFS”, and that often led to people dismissing it. (Including several times at university, with serious consequences for me.)
If I need to, I have learned to describe it as a serious disability. It is serious, and it hopefully gets the point home better.
On rare occasions, I may describe the experience of living with CFS. It’s like having a severe flu without the throat and nose symptoms. It’s like being underwater. It’s like living in a fog. It’s like being a laptop with a very poor batter that doesn’t charge and drains quickly.
I may also describe what I can and can’t do, and what my daily life is. I am in bed most of the time. On most days, I can do things a few minutes now and then, with hours of required rest in-between. I am unable to do anything that’s especially exerting, like reading a book, lifting something heavy, walk fast or run, and so on.
I may try to describe the brain fog. The immediate experience is of living in a fog, or having cotton in and around the head. I am unable to process information very well. I can’t read books or longer articles, or anything complex. I can watch movies in short segments, maybe 5-10 minutes at a time. I can hold a conversation for only a few minutes. I often have trouble finding words. My memory is very poor.
I may mention the Post-Exertion Malaise (PEM), which is one of the most debilitating and confusing aspects of the illness. After exertion, and in the best case, I need hours or days of rest. In the worst case, and very often, I crash. All my symptoms worsen dramatically, I lose my ability to function, and I am in bed without being able to talk. This can last for days, weeks, or sometimes months.
There are websites and brochures I can share that describes the disease. I haven’t done this very often, although it probably would have been a good idea and could have made things easier for me.
A BIT MORE
After writing this, and out of curiosity, I wanted to see what ChatGPT 4o has to say about CFS and these topics. I first asked for a brochure for friends and family, and then a general text. See below.
Understanding Chronic Fatigue Syndrome (CFS)
A guide for friends and family
What is CFS/ME?
Chronic Fatigue Syndrome (also called Myalgic Encephalomyelitis, or CFS/ME) is a serious, long-term illness that affects the body’s ability to produce and manage energy. It impacts multiple systems in the body—immune, neurological, metabolic, and autonomic. It’s a biological condition, not psychological, and can be severely disabling.
It is not the same as ordinary fatigue. Rest does not fix it. People with CFS/ME often face a complete collapse in energy, function, and quality of life. The effects can be life-altering and long-lasting.
Core Symptoms
The most defining feature is something called Post-Exertional Malaise (PEM). This means that even small amounts of physical or mental activity can cause a delayed and serious worsening of symptoms that lasts for days, weeks, or longer.
Other common symptoms include:
- Extreme, unrelenting exhaustion
- Brain fog (difficulty thinking, focusing, or remembering)
- Sleep that doesn’t restore energy
- Dizziness or rapid heartbeat when standing
- Muscle and joint pain
- Sensitivity to light, sound, touch, and smell
CFS/ME affects each person differently. Some can manage part-time activity; others are largely or completely housebound or bedbound.
Why It’s Hard to Understand
CFS/ME is often called an invisible illness. You usually can’t see it—there are no outward signs like a broken bone or visible injury. Symptoms come and go, so people may appear “fine” one day and crash the next. Because of this, it’s easy to get the wrong impression.
Someone might manage to show up for an hour, but you won’t see the days of rest before or the crash afterward. Their energy is limited and unpredictable.
This isn’t about motivation, personality, or mindset. It’s about living within severe physical limits—whether or not those limits are visible.
What People with CFS/ME Need You to Know
- This is real. It’s not imagined, exaggerated, or “just tiredness.” It’s a medically recognized illness.
- They didn’t choose this. No one wants to live like this. The illness can take away careers, friendships, hobbies, and dreams.
- They’re doing their best. If they cancel plans, go quiet, or need help, it’s not personal—it’s survival.
- Rest is essential. Rest isn’t avoidance. It’s how they prevent further deterioration.
- Pushing doesn’t help. Encouraging someone to “fight through it” can make them worse. This illness doesn’t respond to willpower.
- Support makes a difference. Knowing someone believes them and stands by them eases the emotional toll enormously.
How You Can Help
Even small acts of support go a long way:
- Believe them. This is the foundation of all meaningful support
- Ask what they need. Each person is different. Let them guide you
- Respect their limits. Don’t pressure them to “just try”
- Offer low-stimulation connection. Text messages, short visits, or quiet presence can help them feel less isolated
- Be flexible. Plans may change last minute. This isn’t flakiness—it’s how the illness works
- Stay in touch. Many people with CFS/ME lose friends. Kindness, patience, and presence matter deeply
A Final Word
CFS/ME may be invisible, but its impact is real and profound. It can take away nearly everything—yet many people living with it do so with strength, courage, and grace that often goes unseen.
Your understanding, respect, and steady support can make a life-changing difference.

Understanding Chronic Fatigue Syndrome (CFS/ME): What It Is, How It Feels, and Why It Matters
Chronic Fatigue Syndrome—also known as Myalgic Encephalomyelitis (CFS/ME)—is a complex, multisystem, and disabling illness that affects an estimated 17–24 million people worldwide. It can strike anyone, at any age, but remains widely misunderstood and underdiagnosed. While it often unfolds quietly, out of public view, its impact is anything but minor.
CFS/ME is not about feeling “a bit tired.” It is a biological disease that deeply affects how the body produces and regulates energy, involving multiple physiological systems—especially the immune, neurological, metabolic, and autonomic systems. The effects range from limiting to devastating. In its more severe forms, it is profoundly disabling.
Yet because there is no visible marker—no wheelchair, no obvious injury—it’s an invisible disability, and that invisibility often leads to disbelief, minimization, or neglect.
What Defines CFS/ME Medically
The core diagnostic feature of CFS/ME is post-exertional malaise (PEM). This is not just fatigue after exercise; it is a pathological reaction to even minimal exertion—physical, mental, or emotional—that leads to a dramatic worsening of symptoms, often delayed by 12 to 48 hours. A short conversation, a walk to the mailbox, or a bit of stress can trigger a crash that lasts days, weeks, or longer.
PEM distinguishes CFS/ME from other fatigue-related conditions. It reflects a breakdown in the body’s ability to recover from activity—a failure of cellular energy systems and a dysregulation of how the body handles stress and stimulation.
In addition to PEM, patients typically experience a combination of the following:
- Unrelenting, multi-system fatigue that is not relieved by rest
- Cognitive dysfunction (“brain fog”) affecting memory, concentration, word recall, and mental processing
- Unrefreshing sleep, insomnia, or reversed circadian rhythms
- Muscle and joint pain, and sometimes nerve pain
- Autonomic nervous system dysfunction, including rapid heart rate, blood pressure issues, and dizziness when standing (known as orthostatic intolerance or POTS)
- Heightened sensory sensitivity, such as intolerance to light, sound, touch, or smell
- Flu-like symptoms, especially in early stages: sore throat, swollen glands, low-grade fevers
- Digestive issues (in some cases overlapping with IBS or mast cell activation)
While symptoms vary from person to person, they often fluctuate, giving the false impression of improvement or inconsistency. In reality, most people are carefully pacing themselves to avoid triggering crashes, and what others see is only the surface of an ongoing, carefully managed struggle.
The Medical Science Behind It
Although CFS/ME has been poorly understood for decades—and was long stigmatized as a psychosomatic illness—recent biomedical research has begun to clarify its physiological foundations.
Studies have found evidence of:
- Mitochondrial dysfunction, meaning the body’s energy factories (cells) produce less usable energy (ATP)
- Impaired aerobic metabolism, especially a shift to inefficient pathways when under mild exertion
- Neuroinflammation and altered brain perfusion, especially in areas involved in attention and memory
- Immune system abnormalities, including low-grade inflammation and T-cell exhaustion
- Autonomic nervous system dysfunction, affecting heart rate regulation and blood pressure stability
- Reduced blood volume and circulation irregularities, especially during upright posture
- Gut microbiome disturbances, which may influence immune and neurological symptoms
These findings help explain the severity and diversity of symptoms, and why even seemingly small activities can overwhelm the body’s capacity.
Despite this growing body of evidence, there is still no cure or universally effective treatment. Most patients must rely on self-management, especially pacing and rest, to avoid deterioration.
The Scope of Loss
For many, CFS/ME fundamentally changes the structure and meaning of life.
- Careers are lost or indefinitely paused. Work becomes impossible, or must be drastically scaled back
- Education is disrupted—sometimes permanently—for young people with the illness
- Social life shrinks. Events, travel, or even phone calls may become impossible
- Family roles shift. Some patients need daily care. Others live alone in silence
- Hobbies and passions fall away—not from lack of interest, but from physical inability
- Independence may be lost entirely. Some people require help to eat, bathe, or move
- The future becomes uncertain. Long-term plans are replaced with day-by-day management
This is not just physical loss. It is psychological, emotional, relational, and existential. It often involves grieving the person one used to be—or might have become.
Why It’s So Often Misunderstood
CFS/ME is an illness that hides in plain sight. Because symptoms are invisible and fluctuate, and because people often use their limited energy to appear “normal” in public, others may not see the effort involved—or the crash that follows.
Someone may seem fine for an hour, and disappear for a week. They may cancel plans repeatedly, or go quiet for long stretches. To others, this can look like disinterest, avoidance, or inconsistency. In reality, it is survival.
This gap between how the illness looks and how it feels is one of its most painful aspects.
Even well-meaning friends, doctors, or colleagues may unknowingly minimize the illness. Comments like “we all get tired” or “you just need to push yourself a little” reflect a basic misunderstanding of the disease. For someone with CFS/ME, pushing through doesn’t build strength—it leads to collapse.
A Serious Disability
CFS/ME meets the criteria for disability in every legal and medical sense. It restricts major life activities over long periods, often permanently. Yet because the disability is invisible, it is often overlooked or disbelieved.
Using the word disability is not an exaggeration. It’s a way to validate the reality of the condition and advocate for appropriate support, accommodations, and compassion.
People with CFS/ME are not unreliable, lazy, antisocial, or exaggerating. They are managing an under-recognized, serious, and exhausting medical condition with limited resources and little societal support.
How You Can Help
If someone in your life lives with CFS/ME, here are a few things that make a real difference:
- Believe them. Validation is often the greatest form of support
- Listen without offering solutions. This isn’t about willpower or mindset
- Respect their boundaries and rest needs. Rest is not optional—it’s medical
- Adjust expectations. Understand that capacity can change from day to day
- Stay present. Many people with CFS/ME lose friends and social connection. Gentle, low-effort contact helps more than you might think
In Closing
Chronic Fatigue Syndrome is real, serious, and still widely misunderstood. It is not rare, but it is often hidden—because people disappear when they are most unwell, and because our culture is not good at recognizing invisible illness.
Living with CFS/ME requires immense strength—not in the conventional sense of pushing through, but in the daily discipline of listening to the body, setting limits, navigating loss, and preserving a sense of self in the midst of radical change.
Greater awareness and understanding are essential—not only for better care, but for basic dignity.
Because behind every person with CFS/ME is a story of loss, resilience, and quiet perseverance that deserves to be seen.
