Good explanations have already been provided .. I just wanted to reiterate that Al-Anon, although primarily for the family, friends, loved-ones of an alcoholic/addict, it can also be helpful for anyone who's affected by an active addict --- I sometimes have attended due to frustrations experienced by working with addict(s). It's a safe place for me to talk about my frustrations, thoughts, feelings, and situations that arise (what I go through -- not to complain about the addict) --- I feel heard and validated and reminded that I'm not going insane, and what I can do to take care of me (it's not about "fixing" the addict). Best wishes, Deb
