Sorry you're feeling so bad at the moment. It takes me back to how truly awful I felt a while back. Stopping physically picking up the booze was one thing - but learning how to be happy and cope with living sober was beyond my capabilities alone. Obviously, everyone's recovery is different, but for me working the AA 12-step programme has really helped with both anger (well, rage) and anxiety issues, as well as some other behaviours that were completely detrimental to my life and relationships. It had not only brought me back from the edge ,and a very dark scary place, but has also meant that I really am able to understand, and feel, some kind of inner peace.
I hope you will find some way to ease your anxiety and rage soon.
