Falliblewoman, if you truely can't quit on your own then some form of inpatient treatment is always an option. If you also suffer from depression you will need to treat that also. Alcohol will only make you more depressed in the long run and is the worst possible thing as far as anxiety and depression go.
No one is ever hopeless, depression is very common and many alcoholics try to self medicate and alcohol never works. Sounds like professional help might be the best bet.
