For what its worth....
I remember listening to a brian tracy cd a few years ago, and he suggested that a good way to release anger was simply to find a safe way to express it. Go someplace where nobody can hear you can scream at whoever or whatever your angry at... or wait till there's nobody home and beat on something non-breakable (like a bed or a sofa) with a tennis racket until you can't lift your arms..
Or you could try some EFT, got to emofree.com and check the forums there. I'm sure some people could help you out.
Peace
G
