I'm not a doc but my gut feeling is nah for schizophrenic. I don't think so. You have anger issues, so do I. Yours could be for different reasons then mine but looking at each of our behaviors might not be so easy to tell that.

I get frustrated quickly, paranoid easily, bored of people quickly, become argumentative easily, but I can also be a great person too. I work on my anger issues and mood swings. Those are the hardest for me to deal with. I can keep my depression and anxiety pretty much under check with meds. There are no meds for me for the other stuff. Don't think the worse. Lot's of people have anger issues for different reasons.
