A year ago when in inpatient, I was diagnosed with treatment resistant schizophrenia. 
I was diagnosed with this when beginning treatment with Clozapine.
However today I found out my diagnosis has changed without notice to unspecified nonorganic psychosis. I'm still on Clozapine and have been discharged and have support in the community.

What does this mean then? Do I no longer have schizophrenia? What's the difference between it and unspecified nonorganic psychosis?

I want to stop my medication if I don't have the condition Clozapine is treated for.
I've already always had my suspicions.
