You’re still showing up. Still meeting deadlines, still answering messages, still holding things together. And yet something is off. There’s a heaviness that doesn’t lift after a weekend, and a sense that you’re running on something you can’t quite refill.
You might be wondering whether you’re simply not coping well enough. Or whether everyone feels like this, and you’re making too much of it.
Most of what’s written about burnout describes people who have already hit a wall: signed off work, unable to get out of bed, unable to go on. But many of the people I see in the therapy room haven’t reached that point. They’re still functioning. And that’s exactly why it’s so easy for them, and everyone around them, to miss what’s happening.
Still Functioning Isn’t the Same as Being Well
The scale of this is easy to underestimate. According to the Health and Safety Executive, around 964,000 workers in Great Britain were affected by work-related stress, depression or anxiety in 2024/25, with an estimated 22.1 million working days lost. And those figures only count the people who recognised it and reported it.
The people I worry about most are the ones who look fine. The reliable ones, the capable ones, the ones everyone else leans on. They’re often very good at explaining their symptoms away. The headache is dehydration. The exhaustion is just a busy month. The tension in the shoulders is bad posture. Because they keep delivering, the people around them read their output as a sign that all is well, and so do they.
The early signs of burnout are often small and easy to dismiss. Tiredness that a good night’s sleep doesn’t touch, or waking up already exhausted. Feeling flat, cynical or detached about work you used to care about. Snapping at the people you love over things that wouldn’t normally bother you. Brain fog: losing your thread mid-sentence, rereading the same email three times. Doing the same amount of work, but needing far more effort to manage it. Pulling back from friends, or putting off tasks you’d once have done without thinking.
None of these on their own means you’re burned out. But if several have been building for months, it’s worth paying attention.
What Burnout Actually Is
It helps to be clear about what the word means, because it gets used for almost everything now.
The World Health Organization describes burnout as a syndrome resulting from chronic workplace stress that hasn’t been successfully managed. It has three parts: exhaustion, a growing mental distance or cynicism towards your job, and a drop in how effective you feel at work. Importantly, the WHO classifies it as an occupational phenomenon, not a medical condition, and says the term should only be used for experiences at work.
That definition is useful. It reminds us that burnout isn’t a personal weakness, it’s a response to working conditions. But it’s also limiting. Many people are exhausted by things that have nothing to do with a job: caring for a family member, parenting, illness, or the effort of fitting into a world that wasn’t designed for them. The tiredness is just as real, even if the official word doesn’t quite fit.
Why the Holiday Didn’t Work
One of the most common things I hear is: “I took two weeks off, and I was back to feeling awful within days.”
There’s research on this. A review led by Jessica de Bloom found that holidays do improve health and wellbeing. But the benefits fade fast. By somewhere between about twelve days and a month after returning to work, little or nothing was left.
This tells us something important. If burnout were simply a matter of running out of energy, rest would refill the tank and that would be that. But the tank keeps draining, because whatever was draining it is still there when you get back.
Christina Maslach, who has spent decades researching burnout, describes it less as a problem of tiredness and more as a problem of fit: a mismatch between a person and their working life. With her colleague Michael Leiter, she identified six areas where that mismatch tends to happen: too much work, too little control, too little reward or recognition, a lack of supportive community, unfairness, and a clash of values.
That last one is the one I find people overlook most. You can have a manageable workload and still burn out if you’re spending your days doing things that go against what you care about. Sometimes the exhaustion isn’t really about doing too much. It’s about living, day after day, in a way that doesn’t feel like you.
What We Don’t Know
You may have read that burnout is caused by cortisol “dysregulation”, or that it damages your stress-response system in a specific, measurable way. This explanation is everywhere. The evidence for it is much shakier than it sounds.
An early systematic review, back in 2011, found no reliable biological markers of burnout. A more recent review, looking at 48 studies of cortisol, found the results all over the place: some found higher cortisol in people with burnout, some found lower, and many found no link at all. The researchers concluded that cortisol isn’t clearly associated with burnout, though they suggested the body’s stress response may change as burnout goes on, which could explain the mixed results.
I’m telling you this not to make burnout sound less real. It’s very real. But I think it matters to be honest about what’s known. You don’t need a blood test to prove that you’re struggling. Your experience counts as evidence on its own.
Neurodivergent Burnout: When It Isn’t Only About Work
For many neurodivergent people, exhaustion doesn’t come only from work. It comes from everything: the noise, the lights, the social rules, the constant effort of monitoring how you’re coming across.
Autistic people have described this for years, and researchers have started to listen. In a 2020 study, Dora Raymaker and her colleagues worked with autistic adults to describe what they called autistic burnout: long-lasting exhaustion, loss of skills and abilities, and reduced tolerance to sensory input, usually lasting three months or more. Participants linked it to chronic life stress, masking and a mismatch between what was expected of them and the support they had.
This is different from the WHO’s version of burnout. It isn’t limited to work, and it can affect every part of life. It’s also worth knowing that this research is still young; the 2020 study was small and qualitative. Research on burnout in ADHD is even thinner. But many neurodivergent adults recognise themselves immediately in these descriptions, and that recognition matters.
If this sounds familiar, standard advice to “rest and recover” may not be enough. Recovery often means looking at the load you carry every day, not just at work, and finding ways to reduce it.
Burnout or Depression?
People often ask me whether what they’re feeling “counts” as burnout, or whether it might be depression.
The honest answer is that the line between them is blurrier than most articles suggest. In a large analysis of fourteen studies, Renzo Bianchi and his colleagues found that the core of burnout, exhaustion, was very strongly linked with depression, more strongly than it was with the other parts of burnout. Some researchers now argue that burnout may be better understood as a form of work-related depression. Others disagree. The debate is still going.
A rough rule of thumb many clinicians use is this: burnout tends to be tied to work, and often eases a little when you’re away from it. Depression tends to spread across your whole life, with a heaviness or hopelessness that doesn’t lift during a holiday or a good weekend. It’s a useful starting point, but it’s not a reliable test.
If you’re feeling hopeless, if the low mood has spread into every part of your life, if your sleep or appetite has changed significantly, or if things have stopped feeling worth it, please speak to your GP. And if you’re having thoughts of not wanting to be here, you can call Samaritans any time on 116 123.
If you’d like to get a clearer sense of where you are, the Burnout Assessment Tool is a free, validated questionnaire you can find online. It doesn’t replace a conversation with a professional, but it can help you put words to what you’re experiencing.
What Actually Helps
The usual advice — sleep more, exercise, try mindfulness — isn’t wrong. Sleep and movement do support recovery, and mindfulness-based programmes have shown modest benefits for burnout in research. But on their own, they can feel like trying to empty a bath while the tap is still running.
Research on recovery, particularly by the psychologist Sabine Sonnentag, suggests that rest is not all the same. What seems to matter is psychological detachment: actually switching off from work in your head, not just physically leaving it. She also found benefits from activities that feel relaxing, activities that give you a sense of mastery or learning something new, and having some control over how you spend your free time. An evening scrolling while thinking about tomorrow’s meeting isn’t the same kind of rest as an evening absorbed in something you love.
But the bigger lesson from the research is that the causes often lie outside the individual. Reviews of interventions for doctors, for example, have found that changes to how work is organised tend to have stronger effects than programmes aimed at individuals alone. That’s an important message for anyone who has been told that burnout is a resilience problem. Often it isn’t.
So it can help to ask two kinds of questions. The first is about the symptoms: how can I sleep, move and switch off a little better? The second is about the causes: what is draining me, and what would need to change? That might mean a conversation about workload. It might mean learning to say no. And sometimes it means a bigger question about whether the life you’re living still fits who you are.
When to Talk to Someone
Self-help has its limits, particularly when burnout has been building for a long time, or when it’s tangled up with neurodivergence, or with questions about whether your work or your life still feels like yours.
Therapy can help when rest no longer works, when the same patterns keep repeating, or when you can see the problem clearly but can’t find a way through it alone. It can be a place to slow down, make sense of what’s been happening, and work out what needs to change, at a pace that keeps your life stable.
Trueform Therapy offers one-to-one sessions in person in Cardiff and online across the UK and EU, with a particular focus on burnout and neurodivergent-affirming support. It’s designed for people who are still functioning but struggling: the people for whom “just take a break” has never been the whole answer.
Taking It Seriously
Burnout often looks like “fine” from the outside, especially in people who have spent years adapting to environments that weren’t built for them. That doesn’t make it any less real, or any less deserving of support.
If you’ve recognised yourself here, that recognition matters. Whether your next step is a conversation about your workload, a change in how you rest, or a conversation with someone who can help you untangle it, you don’t have to wait until you’ve hit a wall.
If You Want to Explore These Ideas Further
If you’d like to understand burnout as a mismatch between people and their work, Christina Maslach and Michael Leiter’s The Burnout Challenge (2022) brings together decades of their research in an accessible way, with a strong focus on what organisations can change.
Emily and Amelia Nagoski’s Burnout: The Secret to Solving the Stress Cycle (2019) is a warmer, more personal book about why stress builds up in the body and what helps to release it, written with women’s experience particularly in mind.
