Hi Holly,
You could have written some of the AA Big Book. "Resentment is the number one offender. It destroys more alcoholics than anything else."
" if we were to live, we had to be free of anger. The grouch and the brainstorm were not for us. They maybe the dubious luxury of normal people, but for alcoholics these things are poison".
Perhaps you could make use of a program that understands anger and resentment, and has a solution for it.
