When I was 17-18 or something. The guy I fell in love with in High School (who never had a girlfriend) turned out to be straight.
I slumped into deep depression. I was spending days just sleeping, with no appetite, no drive at all. I felt like everything was pointless. Even though I turned agnostic at 16, I began to believe again in damnation and all that nonsense. The reason I didn't go through with it is a bit of logic,
I'm gay, my life will be hell.
I'm gay, when I die 80 years from now, I'll still go to hell.
I'm gay, if I commit suicide, I'll only go to hell faster.
So no escape.
I chose life.
I only managed to pull out of it like 3 years ago. When I did, the first thing I did was to become a full-fledged atheist, heh. I started to basically just live life as it comes. Of course, the fact that I get a lot more disappointments than successes gets me down a lot. ROFL. But I don't dwell on it too much anymore.
Gay teens are 5 times as likely to commit suicide as straight teens, I think. The main reason? Religion.
