Does anyone else remember it?

Almost certainly less than you imagine. People consistently overestimate how much others notice and remember about them — an effect robust enough to have a name, the spotlight effect.

Should I apologise to be sure?

Once, if there is something to apologise for. Repeated checking and apologising is reassurance-seeking, which relieves the feeling briefly and strengthens the loop.

Why does it get worse each time I go over it?

Because you are rehearsing your reconstruction, not the event, and the reconstruction is biased toward the worst moments. Writing the facts once is what stops the drift.

Replaying a mistake: the loop that runs for days

You said the wrong thing in the meeting nine hours ago and you have now heard yourself say it about forty times. Each replay includes a slightly worse version. You know nobody else is thinking about it, and that changes nothing.

Do this now

Close the loop on paper

5 minutes

Write what actually happened in two sentences — only the observable facts, no interpretation.
Write what you will do about it, if anything, and when. One line. Often the honest answer is "nothing".
Then five minutes of slow nasal breathing, in for five and out for five, hand on the chest.
Each time the replay starts, say "already handled" and come back to the breath. Not an argument — a label.
Put the paper away. If the loop restarts tomorrow, read what you wrote instead of re-deriving it.

Run it with a timer

Post-event processing is its own phenomenon

After a social situation, a detailed review of one's own performance — the post-mortem — is a well-documented maintaining factor in social anxiety. It is biased: it selects for the worst moments, discards the neutral ones, and reconstructs an observer's view that is consistently harsher than any actual observer's. Each pass strengthens the memory of the version you rehearsed, not the version that happened.

Why it feels productive

Replaying delivers a sense of doing something about it, and it briefly reduces the discomfort of having left it unresolved. That relief reinforces the behaviour. It also produces an illusion of prevention — if I analyse this enough, it will not happen again — which is why the loop is so hard to drop even when you can see it clearly.

What shortens it

Two moves. Write it down, because a written account stops the reconstruction from drifting worse each time and gives the loop somewhere to end. And lower the physiological charge: rumination sustains autonomic activation, and slow breathing reduces it, which makes the thought less loud without requiring you to disprove it. Labelling the process rather than debating the content is the third, and it is trainable.

What changes it, over a week

When it starts
Label it — "replay" — and return to whatever you were doing. Labelling beats arguing, reliably.
Once, on paper
The facts, the action, the date. Then read that instead of re-running it.
Twice a day, ten minutes
Slow nasal breathing. It lowers the charge the loop runs on, which shortens each episode.
This week
One deliberate small risk in front of people — speak first, ask a question, be visibly imperfect. The replay shrinks fastest when it has competition.

When this is not a breathing pattern

See a clinician — promptly, and before assuming any of this applies to you — if any of these describe you:

Replay accompanied by low mood or hopelessness for more than two weeks
Intrusive images of a traumatic event rather than an ordinary mistake — that needs a trauma-informed clinician
Avoiding work, social situations or people because of it
Not sleeping because of it, several nights a week
Any thoughts of harming yourself — contact your doctor or a crisis line today
