As a friend, get it sorted out asap. It will only get worse as you get older and one day you'll just have a disorder or a drug addiction or both.

There's plenty of free ways to talk to a counselor or therapist, and you just keep trying out different ones until you find someone you like. But they will help you find ways to deal with your problems that will make your future self capable of being happy and fulfilled instead of miserable and alone.
