I can relate. I had no certain singular triggers to drink. If it was rainy, I drank. If it was sunny I drank. I had no clue why.
Now I understand it's because I'm an alcoholic.
It took me a long time to become an alcoholic and it took me a long time to unlearn how to not drink. And many, many failed efforts. Heck, I joined here like six years ago, (under a different name) I and I just got three years sober.
I was convinced that I was one of the unfortunates, too. Then I became honest with myself. I went to AA meetings and learned there were other people just like me. It was a revalation. I thought I was alone and doomed to drink myself to death. That proved not to be the case.
Never give up. I remember how I drank, the viscious hangovers and the wasted time. That's what keeps me sober now.
Hang in there. There is always hope.
