Well I'd like to throw in a word here, just saw this thread and it peaked my intrest, I myself have suffered depression for roughly 2 years now and have decided to stay off of medication and trying to drown said problems with alcohol, all I can truly say is try and find things that make you feel good like, spending time with your girlfriend or even just mellowing out to some music.
Just don't make the same mistakes most people like myself make and just think about it too much because I swear it'll eat at you and make you cave in or even have another "episode".
Just try to keep a clear head and spend time with people that make you feel better and a bit more cheerful, rather than be on your own with your maniacal thoughts making you go into the mood swings etc.
Hope that's helped, best of luck to you o/
