I was a Christian for years, and had really bad delusions about it, finally I realized that it was ALL delusion and the bible is just a book of magical myths.
I dropped my faith 100% and have never felt better. I also dropped all my delusional thinking along with my faith in an imaginary friend. I haven't had any delusions since I became a rational naturalistic atheist.

I am happier than ever in my life without faith, I highly recommend it.
