Am I a psychopath

My therapist tells me I am most likely a psychopath, he had me take a screening exam and I got a pretty high score. The main reason he thinks this is that I have a really big issue with lying and also a lack of empathy and remorse. Im already diagnosed with schizophrenia for about a year, and now this. The thing is I know lying and manipulating is morally wrong, but I get almost a rush from doing it. Is it really possible that I am a psychopath?
