Yeah man, stuff that happens when you're young stays with you, it sucks. But once you can come to terms with it and just let the past be past, you can [for the most part] just look at what's here and now. But man, SUICIDE?! What the fuck! Don't let anybody make you feel that way. Don't let anybody push you that far, no matter how hard they try. In any case, my point is: YOU'RE WORTH MORE THAN THAT. I've felt depressed and probably even suicidal before, but dude - you just have to realize that you have a life ahead of you, and you can do whatever you want to with it.
It happens to a lot of people, why.. who knows really. Could be chemical imbalance, could be past.. no one knows for sure. I know its hard, cause I feel it more than I'd like to, but don't let it control your thoughts.
shit man people suck but suicide never worked for me.. i either didn't cut deep enough or the trains just never came when I would pass out on the tracks. <-- stupid little kid was I. so fuck it I gave that up were stuck here just live it up just go hang with the rest of the "freaks" who are stuck here against their will its always helped me.
