Do you know your early signs of psychosis?

I remember asking my pdoc last year and he said when I start feeling paranoid and suspicious of people it could be early signs of psychosis.

I'm convinced that an Assistant Principal (I'm a teacher) at my work is out to get me to fail and is intentionally sabotaging my career ... I've come to this conclusion since last week Friday

I don't know if it's just because I'm so depressed that he's plotting against me or if it's because I'm so depressed that I think he's plotting against me but isn't.

Omggggg this whole post doesn't make sense.
