I'm sorry to hear that you're depressed. If you don't mind sharing, what else have you tried? Isn't alcohol a depressant? I'm no psychiatrist but it seems paradoxical that alcohol would help with depression
Isn't depressant just the opposite of stimulant? I don't think it has anything to do with depression the syndrome.
It doesn't, but there is a connection: for people who have a predisposition, alcohol is risky in that it can trigger a depressive episode. Typically one of the first things a psychiatrist or therapist will tell you to do in such a situation is to stop drinking. The GP's experience (that alcohol helps their depression) is not typical, but everyone is different.
