I failed an imp xam..i have the urge to cut though i stopped for three wks....helllp?

Just stay strong. Nothing is as bad as harming yourself. Getting a bad grade is not the end of the world it is just one day of your life, by next week you will have already forgotten about it. It sounds like you have been doing great, not cutting and all. If you decide to cut that will just make u even more depressed because you will be mad at yourself that you did it after quiting.
