Anger was a big problem for me in early sobriety. I stayed angry for about 6 or 7 months. I need ear plugs when I read my diary from that period!
I go to AA and have a sponsor and that helped me navigate my way through the stormy waters: I discovered in early sobriety that I was denying my past, all the damage of my childhood, and essentially who I was.
It wasn't easy finally cleaning the mirror and actually seeing who I am.
but, there is a light at the end of the tunnel.
I'm glad I finally discovered the damaged child within because I can finally do something about it, forgive, heal, grow up and move on.
Otherwise I would still be walking around damaged with a drink in my hand saying "I'm okay, really".
I know it sounds odd but the anger is a good sign. It means that you aren't choosing the numbing effects of alcohol to deal with problems.
