Keep in mind, your current education is absolutely free, and you must take advantage of that. If you leave your home, it's going to fresia everything up for you, and you will lose your most logical direction for escape. Really, you should pursue professional help from these websites you've been given, but you've got to try to graduate from high school. A high school diploma is so important, because a GED doesn't look as good. You seem to be a smart kid, and you should embrace that. You have to be happy with what you have to be happy with, and your brain seems to be a pretty good asset.
Think it through, find help, and try to continue a forward motion in your life.
