Hi MNVikes. There are a lot of really wonderful people in AA, and a fair number of SR folks use AA, it seems to me.
I have been to a fair number of AA meetings, early in my career when I thought I was losing my grip on my drinking (I was). I don't know how people could have been more welcoming and supportive.
There are "open" meetings, meant for people who are not ready for...or don't feel they need...utter anonymity. Guests and newcomers are most certainly welcome.
And there are "closed" meetings, only for those who identify as alcoholic.
Others here will be along to comment, I'm sure. I believe you would feel very welcome. Anxiety is natural, but they will put you at ease.
