It's difficult to talk someone out of suicide. I went through it, had alot of serious depressions where i had tried to end it all.
In all honesty, life changes. I don't know what it is, hormones, experience, whatever... But life get's better than it was. You don't feel out of control, and under pressure all the time. It's like the world does a complete backflip.
But whatever, I'm not a psychiatrist or a bible thumper that thinks all life is sacred. I think you should have the right to do whatever you want with yourself. I'm just speaking from my own past experience and how I see my life today. It's very different, and I'm glad I can experience it.
