I'm not sure what other people think. I've learned in AA what other people think about me is none of my business. I have told my sister, wife, and best friend. What's interesting is my cousin is really struggling right now and my sister told him and his parents (my aunt and uncle) that I was going to AA and may be able to help. At first I was taken back a bit for her "outing me", but upon further examination I have no problem with it. Step 12 (even thought I'm not there) discusses working with other alcoholics and carrying the message to them. I hear it's how I stay sober is working with other alcoholics so I'm completely open to it.
I am what I am. It doesn't matter what "label" you put on me I am just me. I have tried to accept my alcoholism as a part of me. As long as I don't take the first drink and try and do the next right thing good things will happen.
