Oh, well, unmake the noose. Trust me, it's not worth it. From someone who's been there, your teenage years are not a deciding factor. Killing yourself right now would result in missing the good parts of your life. There are low parts, but Moau, it'll get better for you, hopefully. You just have to hold out bud, and if you've got a problem, consider going to someone you trust and talking to them about it.
