Hi Fun,
It does sound like you have things to be angry about. I have things I can be angry about too, but what good would it do? We all do things while we're drinking that we wish we hadn't and that can never be undone, no matter how much we want to.
Try to step out of the anger and move forward. Acknowledge to yourself how angry you are and then put it aside. It will serve you no purpose in staying sober or living your life in the future.
Love, Anna
