I might be demon possesed.

I'm taking world religions in college right now and as part of a research paper have had to read about Catholicism.  In part one book there are 7 "symptoms" listed that may indicate authentic demonic possession.  Even when I'm calm I have arguably 4 of them.  So there's a good chance I got a demon in me.  But for that to be true the book the belief is based on would have to be true and since I view it as complete nonsense it's just laughable.
