I don't think there is such a thing as a complete cure. I've been dealing with it since I was a teenager and I am now 50. But since being put in a partial hospitalization program after my last stay in a psych ward, I'm beginning to recognize some of the signs of depression when they start, even when my mind is in denial that I'm getting depressed. Lack of sleep was always an issue, so I can't rely on that, but showering, motivated to get out and socialize even a little is something I do now, and when I don't, I know that I'm beginning to slip again and I talk to someone. Good luck.
