The only thing I want to add is that AA is not the only option, nor even the most effective one. But it is the one with the lowest barrier to entry - you just look up where a meeting is, and you show up. No charge or anything.

However, if AA doesn’t help (and there are plenty of people where it doesn’t), there are a bunch of other options. Some are very casual group support events (but with a licensed counselor), all the way to in-patient clinics, and everything in between.
