I also used alcohol to self medicate, looking back mostly for my anxiety. Towards the end of my drinking though even that didn't work. I was mainly drinking to simply avoid a racing pulse and heart palpitations, the anxiety never left at all no matter how much I drank. That was when I decided to quit as well. I don't really consider it a "rock bottom" because no matter how bad things get, they can always get worse - until you die of course. But it was the moment I finally realized I was slowly killing myself with alcohol.
