Please help, I have issues? My life may be lost?

hate say this but if you want to really get better, cut out the drugs and the Taco bell. you are 15, and that is a very turbulent time. but if I were you I get some counseling as soon as possible. it seems like everything is getting very negative. I think you are very unhappy, and I am sorry for that. but you have to make an effort to improve your situation. is there an adult you can talk with who won't be judgmental? try that and get some help from a professional as well.
