You need to get yourself into a good rehab for recovery. After you have done and that, then attend AA meeting regularly. You will see once you have achieved sobriety, everything else will fall into place. You have got to stop the drinking first, the consintrate on the depression. Depression does cause alcohol abusice but, the driking has got to be treated first so you have a straight mind to deal with the depression. After rehab, you may even find you no longer are depressed.
Hope this makes sense.
I use to work drug and alcohol rehab BTW.

Any other thoughts of help here?

am also severely depressed for vey different reasons but one thing I have become aware of is that alcoholic drinks do not solve the problem. If anything they just put a figurative highlight on the problem and you get into the habit of usng it to wash away your gargantuan emotions. Seeing doctors will help, but don't give away too much and try and get into contact with a pro psychologist or someone similar, talking helps, and your perspective on life alters. You may be aware of your condition but aftr evaluation you will realise that you generally seem able to enjoy the finer things more than before.
