The most important thing to deal with is whatever is most on your mind. The fact that you think it shouldn't be on your mind is irrelevant. It's there, and it's there for a reason.
I am nearing sixty now and the rage is gone. I sort of miss it sometimes. I never did anything stupid, to my abuser or to myself, or not much. Never had a satisfying victory. I didn't set out on a path of peace, climb the mountains of Tibet, or have some brilliant insight. I just carried on, and things sort of faded.
