Hello.
It seems hearing voices is a major problem you are facing right now. And the other problem is the need to hurt yourself. It will be difficult to diagnose anything online, but your symptoms do seem to be a part of psychosis. Please consult a Psychiatrist for a thorough evaluation and diagnosis.
Take care.
