"I'm stressed", "I have anxiety", "I'm burnt out". Over a drink the three sentences mean the same: something is wrong and you cannot take any more. In a consulting room they mean three different things, with different causes and solutions that look nothing alike. Confusing stress, anxiety or burnout is not a vocabulary problem: it leads to applying the wrong strategy for months. This guide explains how they differ and how to work out which one is yours.
Three words we use interchangeably that are not the same
The quick difference, before the detail:
- Stress responds to a specific demand you can point at. It has an identifiable culprit and tends to ease when that culprit goes away.
- Anxiety is an alarm that goes off with no clear threat in front of you, or out of proportion to it. It runs ahead of the facts.
- Burnout is what is left after months of work stress without recovery. It is not an emotion, it is wear and tear.
All three can coexist in the same person, and usually do. But one of them is almost always in charge.
Stress: the response to a specific demand
Stress is an adaptive mechanism, not an illness. Faced with a demand, the body gets ready: heart rate rises, muscles tense, attention narrows. It helps you deliver the project, brake in time, pass the exam.
The problem is not having it but not coming out of it. The World Health Organization describes it as a state of worry or mental tension caused by a difficult situation, and notes that its impact depends above all on how long it lasts and what resources the person has to respond.
The signs that stress has become chronic are fairly physical: tension in the neck and jaw, headaches at the end of the day, odd digestion, worse sleep, irritability with people who are not to blame. And a very distinctive feeling of always running to catch up.
What defines stress against the other two: remove the source and it drops. The project ends, the move is over, the money problem is solved, and within weeks the body settles back down.
Anxiety: the alarm that goes off with nothing in front of you
Anxiety shares the activation of stress but changes the object. Here no real demand is needed: anticipating one is enough. Thought runs ahead and builds scenarios, and the body responds as if they were already happening.
That is why anxiety does not ease when the problem passes. The project ends and the "what if…?" moves to the next one. Two things also appear that pure stress does not have: avoidance (not doing things just in case) and hypervigilance (monitoring every signal from the body or the environment).
Anxiety disorders are, according to the WHO, the most common in the world, affecting some 301 million people. And they respond well to treatment, which is the part least often mentioned.
Burnout: the wear that comes from work
Burnout is the most recent of the three and the worst understood. The World Health Organization included it in the ICD-11 not as an illness but as an occupational phenomenon: a syndrome resulting from chronic workplace stress that has not been successfully managed. That precision matters, because it marks the boundary: burnout comes from work.
The three dimensions that make it up
- Exhaustion: the energy has run out, and the weekend no longer replaces it.
- Mental distance or cynicism: indifference, sarcasm or rejection towards a job that used to matter. This is the piece that appears in neither stress nor anxiety.
- Reduced efficacy: the sense of not measuring up, that nothing you do is any use.
Someone under heavy work stress is still invested, however exhausted. Someone with burnout has disconnected emotionally to protect themselves. That detachment is the most reliable sign.
Four questions to tell them apart in your case
Ask yourself these four and it usually becomes clear:
- Can you point at the cause? If there is a specific, bounded situation, it points to stress. If you cannot find it, or the distress is out of proportion, it points to anxiety.
- Does it go away on holiday? If two weeks off return you to normal, it is stress. If you come back just as empty, look towards burnout. If you keep anticipating even on holiday, it is anxiety.
- Do you still care? Stress and anxiety keep you invested. Burnout switches that off: it makes no difference how it turns out.
- Is it confined to work? Burnout, by definition, is. Stress and anxiety spread to any area.
| Stress | Anxiety | Burnout | |
|---|---|---|---|
| Cause | A specific, identifiable demand | Anticipation, often with no clear cause | Chronic work stress without recovery |
| When it eases | When the situation is resolved | It does not ease on its own; it changes object | With real rest and changes at work |
| Its own sign | Feeling overwhelmed | Avoidance and hypervigilance | Cynicism and emotional distance |
| Scope | Any area | Any area | Work or study |
| What helps | Cutting load and restoring rest | Graded exposure and cognitive work | Stopping, changing conditions, support |
What happens when they overlap, which is nearly always
In practice they rarely come alone. The most common sequence starts with work stress: the load goes up, sleep goes down, the body suffers. Within weeks anticipation appears, which is anxiety, and with it the avoidance of meetings or compulsive email checking. If that holds for months with no room to recover, detachment arrives, and that is burnout.
That is why the picture should not be treated as one single thing. Cutting the load without working on anticipation leaves the anxiety intact. And doing relaxation techniques without touching unsustainable working conditions is a sticking plaster: the European Agency for Safety and Health at Work insists that psychosocial risks are prevented mainly at the organisational level, not the individual one.
Measure it before you decide: the three tests
This is where three five-minute questionnaires clarify more than weeks of going round in circles. The idea is to have three numbers and see which one stands out.
The Stress Test measures perceived stress over the last month: overload, physical symptoms and coping resources. The Anxiety Test covers worry, physical symptoms and avoidance over the last two weeks. And the Burnout Test measures the three dimensions of the syndrome over the last three months at work, including efficacy, which is the one that usually surprises people.
Compare all three results rather than settling on one. If burnout stands out clearly, the problem is at work and that is where to intervene. If anxiety is the one that rises, the focus is different. And if all three come out high, you have an accumulated picture worth discussing with a professional. They are all in the psychological tests catalogue, free and scored on your own device; the guide on the Mental health test: what it measures, which ones exist and how to read your result explains how to read these scores without over-reading them.
What works for each one
With stress, what pays off most is acting on the load: prioritising, delegating, letting go of low-value tasks and restoring rest. Slow breathing and aerobic exercise measurably lower activation, but they achieve little if the diary still does not fit into the day.
With anxiety, the treatment with the strongest evidence is cognitive behavioural therapy: graded exposure to what you avoid and review of anticipatory thoughts. Avoiding brings relief for hours and reinforces the problem for months, so that is where the loop breaks. We explain it in detail in the guide on Cognitive behavioural therapy: what it is, how it works and what it treats.
With burnout, no technique replaces stopping. Moderate and severe cases usually need a period of real rest, sometimes sick leave, and concrete changes in conditions: workload, autonomy, recognition. Therapeutic work on perfectionism, boundaries and your relationship with work comes afterwards.
And one sign that cannot wait in any of the three cases: if thoughts of harming yourself appear, call the 024 line in Spain (free, confidential, around the clock), 112, or your local emergency number. If what you want is to start therapy and do not know where, the guide on When to see a psychologist: signs, common doubts and what happens in the first session covers what happens in a first session.
If your result worries you or you want a professional assessment, you can talk to Xènia Capel Salcedo, a licensed psychologist (COPC reg. 14982), who offers a free first consultation call and online therapy from anywhere.

FAQ
Frequently asked questions
What is the difference between stress and anxiety?
Stress responds to a specific demand and eases once that demand is resolved. Anxiety runs ahead of events, persists without a clear cause and adds avoidance and hypervigilance. You can have stress without anxiety, and anxiety with no external stressor at all.
Is burnout the same as being very stressed?
No. Burnout is the result of poorly managed chronic work stress and includes something stress does not: cynicism or emotional distance towards work, together with a sense of not being effective. Someone stressed is still invested; someone burnt out has disconnected.
Can I have all three at once?
Yes, and it is the most common situation when the problem has been building for a while. The typical sequence starts with stress, adds anticipatory anxiety and ends in burnout if there is no recovery. Taking the three tests and comparing the scores helps you see which one leads.
Is burnout recognised as an illness?
The World Health Organization's ICD-11 classifies it as an occupational phenomenon, not a mental illness. That does not make it less serious: it affects health, and in Spain much burnout-related sick leave is processed as anxiety or adjustment disorders.
How long does it take to recover from burnout?
It depends on how entrenched it is and whether conditions change. With real rest, adjustments at work and psychological support, most people improve within a few months. Going back to the same environment without changing anything is the most common cause of relapse.
Can the tests tell me which one I have?
They are screening tools, not diagnoses. What they do is measure three different things with the same yardstick so you can see which weighs more, and give you something concrete to bring to a first appointment. The diagnosis is made by a licensed professional after an interview.
