I like to blast Linkin Park. They are so angsty that once all the angst comes out the anger goes away. Try it sometime. Like people say... music calms the beast within.
Deep breathing relieves me when I get mad at trivial things (A videogame, being tricked, those kinds of things), but when something really big happens, I dwell on it for a while, then get back at who made me mad subtely. Hehe.
i get angry at lbp because it loses my saves and then i have to ace 5 levels >:[
i have a weird way of handling anger, until recently i hadn't noticed. i yell loud noises all the time. it isn't angry or anything... it's a high pitched yipp, and is fun to see family annoyed
