I've been through what your going through and I'm sure many other people have too. Personally, I think you need to stop smoking reefer for a while. A long break is a good thing. The first few days will be boring as shit but eventually you won't even think of weed. If you need it so badly to resort to crime and stealing pills than its not working for you right now. Adolesence is a piece of cake for some but for others like me and you its a living hell. But you have to ask yourself one question: Where do you want to be ten years down the road?
