Yeah, I still have a great deal of anger and I've been in therapy off and on for many, many years. I does get better with time, but for me anyway the anger is still there. In order to difuse it I try to remind my self of the repreccusions of inappropriate anger, which I might add can be serious. It helps somewhat. Another way I've learned to deal with it is to try to be more mindful of my own personal needs.
I think for now you are just at the begginning of your journey, so take it one day at a time, or barring that one moment at a time
