I've been suffering from depression since I was 14 and I'm 21 now. It's really hard to deal with and confusing when you first realize that you are depressed because mentally you are going through hell and don't know why or how to fix it, but it gets a lot easier. As I got older it has become easier to understand and live with mental illness, however I'm not sure if anyone is ever "cured" from depression. That may just be wishful thinking. I still get depressed. I don't know if mental illness ever goes away, I think it just get's easier to live with.
