AA is a good one, and there are others you can explore too. I’ve been to multiple different types of meetings and I get something different from every one. (In my own case at this point in my recovery I am going to lots of meetings because I love the social connection and the honesty and empathy and support.)
@SinceIAwoke mentioned a good thread here to get you started exploring:
Take a look, search a few up online, drop in and introduce yourself! You will be welcomed and I guarantee you’ll be glad you went. Go ahead and visit a few different types of meetings too - you may like exploring different approaches, different perspectives.
Welcome to the sober journey. Looking forward to walking it with you
