Sucide?! i cant do this no more?

Its sounds as though you have dealt with more bad things than any one person should ever have to. However, suicide will not solve anything. I know its hard to see right now, but you have to keep pushing foward. You should talk to someone you trust like a school counselor. There should also be a crisis intervention hot line in your area. The majority of your problems do seem really troubling, but it will get better. As far as the friends go, I know it really sucks when youre going through it, but friends that leave you that easily werent really your friends to begin with. You will find more. Just be sure that they are true friends who really care about you. Remember, having a few true friends is way better than having tons that you cant count on. Please, though, find someone to talk to. I think you would really benefit from greif and post traumatic stress disorder counseling.
