I'm only now just unraveling my own anger issues.... up until recently, I really thought I was the kind of person that just didn't get angry. Because of my upbringing, I would suppress my anger back into myself where it would turn into depression.
Two things are helping me right now:
* Working on the limiting beliefs about anger. ("anger is never an appropriate response." "there is no healthy way to express anger." "I must be patient/nice/calm/reasonable instead of angry.")
* Writing about the issues and memories that are involved.
My personal advice is pretty elementary because well... that's the level I'm at.
but coping.org has VERY useful resources on managing anger and all the roadblocks you may encounter.
