I think you're thinking of multiple personality disorder not schizophrenia. What type do you have, if you don't mind me asking.
dissasociative personality disorder, though it is comorbid of schizophrenia, is not only present with schizophrenia, is not a form of schizophrenia, and is not supposed to be a factor in schizophrenia diagnosis.
there are four types of the disease which one do you have? the drugs you mentioned can be used for several types of mental illness
if it's real (which i doubt) just be glad you got meds that help. take them n good luck. its nothing to fuck with.. although i dont really believe you.
