The same is for me....Alcohol exacerbated my depression, the more I drank, the more depressed I felt which made me think more drinking would help my depression....
I've been on 3 different anti-depressants over the years, I did not find the right combination that worked for me.
stopping alcohol has given me about 60-70% improvement....if me life circumstances were better, it would probably be more (my mother is very ill and I ended a long-term relationship in the last year)....
but I can get out of bed everyday, go to work and find some happiness.
I try to practice "the attitude of gratitude" and find something good every day.
