I used to have severe depressions in younger age that lasted for years killing my relationships and career. I tried various treatments but they didn't help. It went away when I learned a few things: first, how to not be enemy of myself - not force myself into doing what I don't want to do, being where I don't want to be. Second, learn how to let important things go out of my control and give life a chance to make me happy. Third, I started figuring out what I really like, and what I really want. It all took a lot of self-analysis, writing and being ultimately honest with myself. It didn't come in 1 day and it wasn't easy, but falling back into depression was a much worse scenario. So there was no silver bullet in my case, just lead bullets. But it worked.
