Just a couple of quick notes on AA from someone who had not even the slightest use for it for 21 years (and now thanks to its program and fellowship has been sober for a little over one):
1) You could, if you so desired, go to a meeting every day forever and not have to say a word, nor have to stand in front of anyone.
2) People choose to what degree they protect their own anonymity, but you'd be hard pressed to find a person in AA that wouldn't go to the ends of the earth to protect yours -- it's literally one of the twelve foundations the fellowship is rooted on. Especially in a small town, where the odds are good you'll run into your neighbor's boss (or your neighbor), a teacher or two, a whole bunch of guys from the bar, and just about anyone else you could imagine.
Welcome.
