For right now - I'm using exercise to help me deal with all that energy. It doesn't make me any less angry, but it does give me an outlet.
I'm learning that it's okay to be angry. I was taught as a child that being angry was bad - so for years, I stuffed. I never got "angry" with my AH. When I was hurt, or upset by something he said, I tried to be "nice" and talk about it with him... and never get upset, or raise my voice. I didn't allow myself to feel. It was NO GOOD.
I am unearthing so many feelings as I travel through my recovery... geez. It feels good just to say, "I'm ANGRY." That in and off itself is a pressure reliever.
There's a great chapter in Codependent No More that's devoted just to anger! It describes (in better detail than I could provide here!) a great process to feeling, processing, and moving on from your anger!
