Do you guys believe that overly religious/spiritual people have an undiagnosed mental illness?

Like I believe in God and have nothing against people who are into astrology, tarot cards, the sun, the moon etc but it’s when they’re too into God or those things that it becomes almost psychotic. Like, they call everything demonic. They overanalyze common/normal things and say you’re going to hell if you participate in those common things. They feel superior or call theirselves “Chosen” ones. They make everything deeper than what it is. I even read an article about a woman who killed her entire family because of the solar eclipse and the ones who say things like “God put this in my spirit.” Or “God told me.” And it’s always something that you can clearly tell they made up in their head.
