Welcome to SR Phan! I'm glad you found us and joined the family.
I also self medicated my anxiety and depression with alcohol, but it didn't take long for that to backfire and make the anxiety and depression much worse. I think you are smart to want to quit drinking before something really bad happens. Alcoholism is progressive and will only get worse if you continue to drink.
I don't know what your drinking habits/patterns are, but if withdrawal is a problem please get medical attention right away.
Again, welcome!
