I finished my drinking at 22, a chronic alcohlic. I had no outside issues, there was nothing and no one left. That's what alcoholism did to me. It runs in my family.
Not everyone who has problems with alcohol is an alcoholic of my type. I'm not trying to offer false hope, but I have met people who hit the bottle because of an issue in their life. For the time they drink, they look alcoholic. But when the issue is resolved, the drinking problem goes away.
Deciding which course to take will require all the honesty you can muster. My suggestion is you make a decision to stop drinking, stop drinking, and see your doctor or therapist to try and deal with those issues. That might fix the problem.
If you are an alcoholic of my type, fixing the issues won't fix the drinking. Then you might need another huge dose of self honesty to deal with that. But at least you will know for sure what the problem is.
