Hi Sally,
I've been struggling with depression since I was 8...alcohol is a temporary, quick fix for me that always leaves me lower. My depression is under control with medication...and I'm still an alcoholic (I just occasionally binge drank instead of drank daily with the depression under control). There have been a lot of good suggestions here about AA and other alternatives - can you look into them?
The only person it is too late for is someone like my brother-in-law, who died of an overdose. One of the wonderful things about being human is the possibility of redemption (and I mean that spiritually, not in the religious sense). AA is working for me and when I finally had had enough, I was broken and as low as I could get. It was die or live.
At the meeting last night, there were several people who had relapsed, one that very day. But they aren't giving up. Please don't give up.
