I've overcome the worst of it, still have a ways to go. What gets me through some of the relapses is just the knowledge that the depression is what is causing the problems for the most part. Alot of the things that get me down are/were silly and its just a phase not easily attributed to realistic problems. If you just remind yourself that it doesn't have to last forever I find it helps. I wake up the next morning feeling good.
But other than that, I'd say be around others without trying to gain pity. Find out what other people like to do and try those things. I know being depressed means you're apathetic as fuck right now but its all about gaining traction and keeping that momentum. Let go of those things you lost. Accept it, have no regrets, and find new alternatives. I especially stress having no regrets. Despite what most people think, you could not have done things differently. Don't tell yourself I shoulda woulda coulda because for all intents and purposes- no, your "free will" factoring into any decision was just a conditioned response based on a chain of cause and effect during your whole life.
