Is this Psychosis or perhaps Schizophrenia?

Hi. I am 23 years old and live in the UK.For about a year now i have been having auditory hallucinations.It is two men in my head talking to one another and they also talk to me.They say that i am worthless and better off dead.The voices are there all the time and i can't get a break from them.Recently the voices have become more sinister.They have told me to harm my family and myself though i don't think i would do that.The voices are very disturbing to me. I am scared that i might eventually start to believe them.I have also been getting messages from the TV.There are times when i really believe that the TV is talking to me and about me.I have also on a few occasions seen a little girl in my house. I see her as clearly as i see everything else.She doesn't talk to me just waves and i wave back. I told my psychiatrist what had been going on and she put me on 2mg of the antipsychotic Risperidone.She doesn't want to diagnose me with anything yet.Is this Psychosis or perhaps Schizophrenia?Thanks for your time.Take care everyone.
