I have been going to Al-anon for two years. All but four months of those two years I have not had anyone directly in my life that struggles with Alcohol.
There are only open meetings where I live, but I would have no problems going to closed meetings if they were here. Your posts to me sound like you are a "friend or family" of someone with an alcohol problem. For me what I learned transferred over to affairs, bipolar (with another loved one etc). I am glad you posted.
