what to do in the next hour
- Sit down or lean on something. Feet on the floor, back against a wall. Your body isn’t holding you up right now, and it doesn’t have to.
- Make the out-breath longer than the in-breath. In through the nose for four, out through the mouth for six or eight. Don’t chase the count, only the ratio matters.
- Cancel whatever can be cancelled today. Don’t settle the argument, don’t write the resignation, don’t call your manager. Decisions made from here get remade tomorrow.
- Say out loud what’s happening. "This has floored me. It will pass." A state with a name takes up less room than one without.
- Get someone on the line. You don’t have to explain — you can just ask them to stay nearby, or to text back.
- Eat something and drink water. On an empty stomach the shaking is worse, and that isn’t character.
The sharp part usually lets go within tens of minutes. What follows — being wrung out — lasts longer, often to the end of the day, and that’s expected.
the symptoms people list
There’s no checklist that lets you settle this yourself, but the set is recognisable. In the body: a hammering heart, air that won’t come, hands shaking, nausea, a head or a stomach that hurts. In the head: thoughts scattering, a simple decision turning impossible, everything grating, tears arriving unasked. In behaviour: a person either goes off, or switches off and lies facing the wall.
Two things matter more than the list itself. Half of these signs are the same in a panic attack, in burnout and in depression — so counting them up gets you nowhere, and the states are told apart by how it started and how long it has lasted. And the lists differ from source to source: three groups of signs in one, five in another, each presented as settled. That’s a sign nobody holds a firm boundary here.
why there’s no such diagnosis
No doctor writes "nervous breakdown" in your notes: the phrase isn’t in any classification of illnesses. It’s an everyday word, like "my heart played up" — clear enough, and explaining nothing.
Here’s what stands in its place. ICD-10 has a block called F43, "reaction to severe stress, and adjustment disorders", and inside it sit acute stress reaction and adjustment disorder. The first is about the hours and days after a blow; the second about the weeks and months when life has changed and you can’t settle into it.
When the classification was rebuilt for ICD-11, acute stress reaction was moved out of the disorders: the revision proposals describe it as a normal phenomenon that may nonetheless need clinical help, and the final grouping of stress disorders doesn’t list it — there you find PTSD, complex PTSD, prolonged grief disorder and adjustment disorder.
For someone searching right now for what to treat, that translates as: this isn’t your mind breaking. It’s your mind answering an overload, and it happens to people with no diagnosis at all. Help may still be needed, and asking for it is ordinary.
is it a breakdown or something else
One phrase covers several states, and they need different help. The quickest way through is to look at how it started and how long it has lasted.
A few minutes of it, with a hammering heart and the fear you’re dying. Peaks in two or three minutes, then recedes slowly. That’s a panic attack, and it works differently.
Months without energy, and weekends don’t give it back. Work stopped working, people feel like one more task. That’s closer to burnout — it’s about a load carried too long.
Nothing pleases, nearly every day, for more than two weeks. Don’t wait this one out: the signs of depression are set out separately, and depression responds well to treatment.
Anxious in the background, with no object, body always braced. That’s anxiety that won’t let go — a permanent hum rather than one hard evening.
Snapped at the people closest to you, then the shame. Same word in English, different machinery: when everything is irritating.
Often two of these are true at once — burnout, say, that ended one evening in a collapse. That’s an ordinary combination, and it explains why "treating the breakdown" on its own doesn’t work.
what not to do
Take deep breaths. The most common advice in this subject and the least useful: several big breaths in a row without a long breath out wind the breathing up instead of down — the head goes light, the fingers tingle. The opposite works: a longer out-breath. The mechanics are in why you can’t breathe when anxious.
Watch your breathing. Also popular, and for some people it starts a loop that’s hard to leave — when you can’t stop thinking about breathing. Safer to hand the rhythm to something outside you: a timer, a count, another voice.
Settle it with alcohol. Quieter tonight, louder tomorrow: the nervous system springs back the other way. That’s hangover anxiety.
Demand that you pull yourself together. One more demand for someone who already has more demands than strength.
when to see a doctor
Some of this can’t wait. If thoughts of hurting yourself have appeared, if your speech is going, if you’re seeing or hearing things, or you can’t get up and do ordinary things — that’s a doctor today, not an appointment next week. The numbers are at the bottom of this page.
The rest is a reason to go without panic, but to go:
- it’s as heavy or heavier on the third day running;
- sleep hasn’t come back for more than a week;
- this repeats — every few months or more often;
- since that evening you haven’t been able to return to work and ordinary life;
- it landed on top of an already hard stretch: a loss, a divorce, an illness.
A GP is a reasonable first stop: an underactive thyroid, anaemia and vitamin deficiencies produce the same picture, and blood tests settle that. After that, a therapist or a psychiatrist.
If you want a number to bring to the appointment, we have two scales clinicians use: the anxiety test and the depression test. They don’t measure a breakdown — there’s no scale for that — but they measure what may be sitting underneath it.
what "treatment" means here
What gets treated isn’t the breakdown but what stands behind it, so the method depends on the finding. If it’s a reaction to one specific blow, talking therapy and time do the work; if depression or an anxiety disorder is underneath, both have protocols and the protocols work. Medication is chosen by a doctor, and in this subject that matters more than usual: sleeping pills and sedatives borrowed from a friend are a common reason things get worse.
About time off, separately. A state that stops you working is grounds for it — but the note comes from a doctor, and for that you have to get to one. Taking unpaid leave to lie down helps less often than people hope: it returns some strength and changes nothing about what drained it.
Breathing occupies a narrow place in that row, and it’s worth naming honestly: it carries you through tonight and doesn’t touch what’s behind tonight. What it does have is availability — everything else starts with an appointment.
short answers
How long does a nervous breakdown last?
The sharp part is usually tens of minutes, for some people up to a couple of hours. Being wrung out afterwards lasts longer, to the end of the day or into the morning. If it’s just as heavy on the third day, that’s no longer one hard evening and it’s worth seeing someone.
Can one event cause it?
It can, though more often one event turns out to be the last in a row. Which is why, when people look back, it isn’t that evening that explains it but the months before.
How do I tell a breakdown from a panic attack?
By the onset and the length. A panic attack starts sharply, peaks in two or three minutes and is built around a bodily fear. A breakdown unfolds slower, lasts longer, and feels like "I’m out of everything" rather than "I’m dying right now".
What do I say to someone having one?
Fewer words, more presence: "I’m here", "we’ll sort it out later". Don’t argue with the content and don’t look for who’s to blame. The steps are in how to help someone having a panic attack — the mechanics are the same.
Can I go to work the next day?
Sometimes, and that isn’t heroism. But if the day passes in fog and mistakes, it’s wiser to take a pause through a doctor than to earn yourself another evening like the last one.
Does breathing help with a nervous breakdown?
In the acute hour, yes: it brings the pulse down and gives the body something to stand on. After that a different kind of work begins, and it isn’t quick — what brought you here doesn’t come apart in one evening.
