The surprise, for a lot of people, is that heartbreak turns out to be physical. Not metaphorically — the chest genuinely aches, food genuinely will not go down, and three a.m. becomes a place you live. This page is about the body’s half of a breakup: what it is doing, how to keep it maintained, and the honest line where a website hands over to a doctor.
What the body thinks is happening
The body does not file “breakup” under sadness. It files it under threat. A central attachment has been torn out, and the stress machinery responds the way it responds to any alarm: vigilance up, sleep light and broken, digestion deprioritised, heart doing odd things at rest. Emotional pain also runs on machinery it shares with the physical kind — “it hurts” is not a figure of speech.
None of this means something is wrong with you. It means the system is doing exactly what it does under acute stress — and acute is the operative word: for most people this phase eases as the first days become structured weeks. Your job during it is not to perform wellness. It is maintenance.
Food: lower the bar, keep the schedule
The appetite switch is off; arguing with it doesn’t flip it. What works is dropping the standard and keeping the rhythm:
- Small counts. Toast counts. A banana counts. Soup, yoghurt, a milky drink — liquid calories are still calories, and cold things sometimes go down when hot meals refuse.
- Schedule beats hunger. Eat by the clock, not by appetite — something at the times meals used to happen. You are keeping the machinery running, not dining.
- Easy beats virtuous. This is not the fortnight for a nutrition project. The freezer, the tin, the meal a friend drops off — all legitimate.
If a friend asks what they can do: food is the answer. It is concrete, it is deliverable, and it removes a decision from a person who has no decisions left.
Sleep: aim for rest, not for a good night
Chasing “a proper night’s sleep” during the acute phase mostly manufactures a second failure to lie awake with. Lower the target: rest, in the dark, at a regular hour. Lying still with your eyes closed pays real physiological rent even when sleep doesn’t come.
The mechanics: a wind-down boring enough to be automatic, at the same hour; the phone charging in another room — in bed it is the rumination loop with a search bar attached; something dull for the ears, because a tedious podcast beats silence, and silence hands the room to the loop. Bad nights will still happen. They are weather, and they thin out with the rest of it.
The shortcuts that cost more than they buy
Alcohol is the classic trade and the worst one: it buys unconsciousness, not sleep — the second half of the night shatters — and it delivers its chemical low onto a nervous system already scraping bottom, usually at exactly the hour the urge to text is strongest. The same logic covers anything else that promises to switch you off: the debt lands tomorrow, with interest.
Over-exercising into exhaustion is a subtler version — training to collapse “so I’ll sleep” adds a physical stressor to a stressed system. Movement helps; punishment doesn’t. A walk is the honest dose.
Where this page stops — and means it
This page describes the ordinary storm, and the ordinary storm eases. Some of it is not ordinary, and pretending otherwise would be the kind of lie this site exists to avoid:
- Days, not nights. If real food or real sleep has barely happened for days on end — go to a doctor.
- Alarming symptoms. Dizziness, fainting, chest pain that frightens you, fast weight loss — doctor, and chest pain that feels wrong is an urgent-care question, not a search query.
- The welded-on darkness. If the sleeplessness comes attached to hopelessness that will not lift, or to thoughts of harming yourself — that is beyond any page, this one included. A doctor, a therapist, or a crisis line is the right reader, today. Going is not an admission of anything; it is using the right tool.
For everything short of those lines: small food on a schedule, rest in the dark, no chemical shortcuts, and days with some structure in them. The first week’s order of operations is here, and what the following weeks look like is here.
