I hear ya! I was born an alcoholic and drank acoholically from 15-39. I now have 5+ months sober and have found a whole new world open to me. You have asked for help and that is the start.
Sounds like you don't have anything to lose so what about inpatient treatment? But do know that SR is here 24/7 and someone is always here to "chat" and give their experience strength and hope!
Welcome to SR!!!!!
