I just wanted to say that I was 20 -- which apparently is freakishly old for this sort of thing -- and it was still a fairly traumatic experience, because I thought I was ready, but I wasn't, not mentally/emotionally, anyway. At 15, you don't stand a chance of it helping more than it hurts you in all aspects of your life.

You've gotten a lot of good responses here -- I hope you take them under consideration. Good luck to you.
