How is one supposed to deal with Anger?

I am temperamental, occasionally immature, moody, prone to whininess. In fact, a lot of things. The one thing I am usually not, though, is angry. In the sense of white-hot, testosterone-driven rage, not really my thing. Usually.

Sometimes, though, it snaps. Fury envelopes me, and I don't know what to do about it. My heart pounds like a piston, I breathe fast, and I can break someone's face. Usually, the mood passes. It leaves me feeling foolish.

I am unsure, though, of whether I should channelise the anger, go and punch somebody in their bloody face, and feel satisfied, or wait for it to evaporate, and feel foolish.

This time, though, I shall NOT apologise. If you want a fight (or even if you don't, but you test my patience), you get one.
