I had a lot of anger issues when I was younger, I have broken multiple noses (though admittedly I feel pretty justified every time it has happened) once I got into a "fight" but it was so one sided it was ridiculous and I almost went to jail for it, but I got community service and had a tit load of anger management lessons which surprisingly helped a lot.

Now when I get angry I am much more likely to put a hole in a door, I still have lingering anger issues but everyone who knows me thinks I am a much calmer man, point in case: once when I was at school some boys used to make fun of me, they were whispering (and not even looking at me) I went over and started a fight with them as I thought they were talking about me.

In the end I went to a school for people who have anger issues which helped a lot along the way and now I am a better man for it. Anger is not a good thing >.<
