I had 1 friend when I got sober, and he was my drinking buddy. We're still friends 31 years later, though I had to stay away from him in early recovery. He still drinks.
Anyhow, I was completely socially ********. Didn't like AA, nor want to be there, but at the time felt I had no other option. I'm happy about that because going there changed my life. I had a great time socializing with only AA people in the beginning, and I learned from that how to make friends in the outside world, and enjoy my life away from the bars and clubs. There is so much more to life.
I'm in a pretty great place today. And I'm certain I'd have never learned to have gotten there without AA. I wouldn't abandon the idea just because they're in churches. I was brought up in Catholic school and quit that God when I was 10 years old. For life. AA has nothing to do with that.
