Suggest Treatment For Schizophrenia

Hello doctor,my name is Jay and i am 24 years old.i believe i suffer from schizophrenia since i'm hearing voices such as believeing that my thoughts are being broaddcasted and a believe that an external force is out there trying to control my thoughts and behaviours.i've been through this for the pass 4 years but i didnt know i was schizophrenic until i read some details online recently which informed me about the symptomps and they all match to what i am experiencing.i do not have fear dealing with it,only that sometimes i get quite agitated.i've never gone to a doctor for this,but in my country its easy to get meds without any prescription.so i read that risperdal is a good one.i just went and bought one yesterday and seeing how it works,so far so good except i feel really "dull".i used to take nitrazepam called dumex/dumolid it used to make me feel good.the question is,is it ok if i take the nitrazepam combined with risperdal?and how much of risperdal should i take per day?looking forward for your help,thanks doctor.
