There is a condition known as kleptomania where the person literally cannot help or resist the urge to steal ... You say you feel bad and don't know what to do, I think it's good you can acknowledge it's bad to steal, but that doesn't make you a bad person or in need of judgment ... If you have a therapist, discuss this with them ... If it ends up that you do have it (kleptomania), then start treatment for it because, yeah, it would totally suck to get caught and tossed in jail over some kind of issue that most judicial systems don't give a fig about whether you can help it or not ... Plus, if you are in treatment for it, then it may even help (reduced sentence, fines etc. ) in the event that you do get caught!
