Ask what tends to be there in the half hour before you flare: a bit of shame, feeling small, an old fear about being left. The anger often arrives to stop you feeling that. Tending to the ache underneath does more for a temper than any amount of discipline aimed at the temper itself.

Irritability is part of depression, and it belongs to the mixed and elevated states of bipolar disorder too. Anger skills are still worth having, and on their own they will not do much if what is driving the anger is a mood that needs treating. The clue is usually timing: a temper that arrived with a whole change in sleep, energy and outlook is a different thing from one that has always been there.

Full muscle relaxation, working through the body group by group, takes about twenty minutes and is worth doing a handful of times. Once your body knows what that release feels like, the single hand version can call some of it back in seconds. Skipping the long version and expecting the short one to deliver is the usual reason people say it does nothing.

There is a difference between letting pressure out of the body and rehearsing the grievance. A walk, a swim, hard cleaning, prayer: all of that shifts the physical charge. Retelling the story with heat in your voice, even to a sympathetic friend, is mostly practising the anger one more time.

This is not getting it off your chest. The target is the surplus energy, so stairs, a brisk walk, or a hard ten minutes of almost anything will do the job. The moment you notice yourself rehearsing what you should have said, bring your attention back to your legs or your breathing. You want to come back tired and quiet, not sharpened.

Pacing the kitchen while you build the case against someone keeps the whole system revved. The same twenty minutes spent counting breaths or noticing your feet usually lands somewhere else entirely. If the argument will not leave your head, make the movement demanding enough that there is no room left for it.
