Is this schizophrenia? Or based on reality?

I was diagnosed a schizoaffective 2 years ago. Before that i was less in touch with reality and had the believe i was a religous leader. But in the past 2 years ive been experiencing that my brain is being controlled by the force of many people that exist in real life. From my neighbor all the way to actors or athletes. They usually play with my head by deleting my thoughts or by mocking me inside of my own body. I have been told this is a hallucination but by knowing this they keep bothering me to the point of homicide and suicide. Is it really an illness or a part of my life i just cant change in any way?
