Yeah, that's the right thing to do. It was a blip - learn from it and move forward. Show me an alcoholic that has never had a blip. We've all had them.
I never did the 12 steps, but I have made amends with people I had wronged in my own way. I also learned about myself and what makes me tick. I did not need AA to do that.
I know I am what people in A.A. would consider a "dry drunk" because I am abstinent outside of A.A., but the "quality" of my sobriety is the best I have ever had. I would not change it.
A.A. works for some people and I'm glad it does. I am not one of them though - I found a way that works for me. I have stolen a few of their sayings though and still use them occasionally.
I am glad you find the social aspect of A.A. to be beneficial, because it can be very difficult to find sober company. Most of my leisure activities are solitary activities because the majority of people my age (early 30s) drink to socialise.
