the only advice I have for you is to think of AA and Al Anon. You've definitely earned a seat in both!
Re the depression, yes, the booze interferes with the meds. And..... you have already answered your question about drinking. You know it is bad for you and that you need to quit.
All I really have for you is a hug and letting you know that you matter and I care.
