Am I sinful for being "delusional"?

I've been diagnosed with "unspecified psychotic disorder" I suspect to be schizotypal personality disorder. I have many strange beliefs supposedly due to my "disorder." I believe that the elites of the world are possessed by demons that leave their hosts' bodies in order to gangstalk the general public and feed the information back to their hosts. I believe I have magical powers and that I can defeat demons in my dreams. I also believe that everything is sentient to some extent, even the walls and floor, and the wind and the trees. I also try talking to people from other universes.

My psychiatrist and the people around me insist that I'm delusional. It's truth to me, though. Naturally, one of us must be wrong. Maybe I'm right about these things, or maybe they're right. Most likely it's a mix of the two.

The complication lies in the fact that I spread this knowledge wherever I can. I talk to people irl about it, I spread it online, and I've even written notes around my city for people to find with my knowledge in them. If I'm wrong, am I sinning by spreading my "delusions"?
