I'm worried that I'm crazy.?

Nobody can "diagnose" you here. But I would suggest that you go and speak with a psychiatrist. Either way- that is what you need to do. There is no such thing as an online psychiatric diagnosis. Too much is involved- like the doctor has to see you- how you speak and sit and walk and talk to make an essment of your emotional state. What is weird is that you know that you are having auditory hallucinations and that you think what you are experiencing is not real. That makes it sound a lot more like some form of neurosis. If so- then you would probably do best with psychotherapy. If however it is a form of manic depressive illness, then medication is the therapy of choice.
