Hey, AA isn't a social club, waiting to analyze you and discuss your membership! Talk to someone, GET A SPONSOR!!! It doesn't matter if you are shy. That doesn't mean a thing!
Do you want to get sober? Go Get It! It isn't going to come to you, I promise.
I was the Treatment Facilities Rep for my group for 2 years, and all of the prisoners used to ask me "How do I get in to AA?" Just go and get it. If you truly need to get sober, you'll go to ANY length to get it
