Chronic motor tic disorder (manic-depressive illness) is a psychiatric condition that needs to be managed under close supervision by a trained Mental Health Professional to prevent any relapses. For a better quality life, you need to take the medications on a regular basis. From the information that you provided, it seems that you are having auditory hallucinations (hearing voices when no one is around) which can be a symptom associated with Schizophrenia, Bipolar disorder , substance abuse etc. Hallucinations are disturbing and sometimes can be dangerous to self or others. Medications are proven to be effective in the treatment of this condition.
I would strongly recommend that you get a comprehensive evaluation by a physician/ psychiatrist for adequate diagnosis and treatment. I hope this information is helpful to you.
