I've got anger problems too. Try some of these ideas on for size.
WHEN YOU ARE ****:
don't do anything rash. this is very important. many times when you're really **** off, bad ideas sounds like good ideas. I've actually considered suicide, killing people, running away, when I was really really **** off. These are not good ideas.
don't listen to what your heart is telling you. Your heart is an idiot. It'll tell you what you want to hear, and pretty much only that. It's the "yes-man" of the human psyche.
chill out. go somewhere quiet. think logically about the problem. If you are considering a resolution to the problem, think as far into the future as you can. Ask yourself, "is this really what I want to do?" Again, listen to your BRAIN.
Don't fight back. Fighting makes things worse. (yes, even if you're bigger.) Don't talk trash. Don't go for the last word. Consider getting them back sometime far in the future. Usually by the time you were supposed to go through with that plan, you'll be cooled off and thinking rationally.
Rational is good.
mmm-yes.
If nothing else seems to work, have a friend or yours tell a joke, or watch a funny movie, (gotta plug my site ;D -The Crucible, or Taffy of Death.

Also try to keep in mind that when you are **** off, things don't usually make a lot of sense.
Do what you can.
and try not to kill anyone-
blood doesn't come out of carpet very well.
