From what I've read from your posting, this anger actually sounds like a very good thing for you!

You are FEELING anger, and you even know what feeling you are feeling! That's great!

I know being that angry isn't comfortable. But feeling our anger about the wrong done to us is very necessary. Others here have offered some very good suggestions for how to get the tension from all that anger out of your body, I would try those things. Take care of yourself.
