I also suffered from depression most my life....until a made a monumental decision.
I came out transgender. Coming to terms with the fact that my male body didn't match my female soul took a lot. I was in denial my whole life, and it took a suicide attempt to finally come to terms with it.
Now after two years of transition, my life has rebuilt, and I have happiness that I never knew would ever be possible. Life is hard, but I actually have dreams for my future now.
