Despite not feeling comfortable giving tips to someone underage, I don't think people should undermine how you're feeling because of your age. There are people here (myself included) who wish they would have ended it all at your age or younger rather than prolong their suffering even more. Life isn't a guarantee and you can't know whether your life will improve or get worse and by then you'll only regret that you didn't go sooner... on the other hand your life could improve and you'll be glad you didn't go through with it. In the end only you can decide and take the chance.
