I am sorry but I had to take a couple of words out of your post. We are not allowed to discuss suicide or self harm here. I am sorry. I do have a few sites that you might want to visit though. I will post them.
I hope that you start feeling better soon. I wouldn't leave school to work yet, you wont be able to find a descent job without an education. More treatment might be good for you. You need to build your self confidence up. I can tell by what you write. So that is something that you need to work on. You are a good person and don't deserve to be bulliled.
Here are a couple of sites that you might want to check out.
I hope that you check these sites out and find something that will help you. We get a lot of teens on this site too. So hopefully you can hook up with somebody your age and get some support.
