Are you working the AA steps or are you working another program? AA shows you how to write out and share your resentments, shortcomings and wreckage with another person. It is part of the process of clearing away all of your mental baggage caused by your alcoholism.
I am just on the edge of doing that with my sponsor and he is guiding me through the process. I am not sure how other programs achieve this but maybe others on the site can help out with that.
No matter what, dealing with the wreckage is going to be tough but you are sober now, and for me at least, that means that I am not adding to the list of stuff I did. That's a good start.
