A great article by Chase Amante about how to conquer depression:
There's another element of depression that I realized much later on, and has subsequently borne out in scientific research: namely, the importance of feeling in control. People who feel very in control of their lives have markedly lower rates and risks of depression that people who don't feel much in control of their lives. Which makes sense; when I felt depressed, the best way to describe that feeling, really, was feeling helpless. Feeling like I had no idea what to do to change my life, and no resources at my disposal to start changing even if I did know what to do.
