Hi,
I also had depression long before I began drinking. I was kind of able to manage the depression until a time when things came together and I couldn't deal with it anymore and I began to drink. What a mistake that was! So, I had to get my depression properly treated before I could stop drinking. When I was depressed, I honestly didn't care enough to put in the work I needed to do, to recover. I began taking antidepressants, which level the playing field for me. Years later, I am still taking them and still recovering.
Have you talked to your dr about the depression?
