For me, my workouts really help; it's a big "screw you" to depression. Going out whenever you can, being around people, ... basically trying to force yourself to do what depression holds you back from; it's not easy, that's for damn sure, but in can be doable. I also find expression helpful, and that, for me, comes out in my guitar stuff, but there's also poetry, drawing, painting, and other creative forms of expression. Most importantly, if you want to beat it, don't give up! Never ever give up.
