Welcome Peter! I think it is natural to be nervous about your first AA meeting. I was so nervous my first meeting I accidently found myself in a Cocaine Anonymous meeting they hold in the same building! You never have to share in a meeting if you don't want to. If called on you can always say "I am just here to listen." You don't even have to say "I am an alcoholic" if you don't want to. I would recommend going to at least three or four meetings to give it an honest try. Take what you want and leave the rest. If you want what the people there have then the next steps would be reading the book Alcoholics Anonymous (we call it the big book) and finding a sponsor to help you work the steps. For me AA did more than save my life. The people in AA taught me how to live because in 30 some odd years of life I had never bothered to learn. Keep coming back.
