I had depression because of cognitive dissonance.
Here is what I've observed because of mental disorders in the jw's: My mom married my step-dad when I was 7. She had just become a jw and he was fairly new to it as well. A year after they married we moved to Utah to preach to mormons because of the whole "move to where the need is great" BS, plus the congregation in California just wasn't "spiritual enough". Eventually he became an elder. After some issue in the congregation he came to the conclusion that mormons had done some long term infiltration in the hall and they were coming to get us. We jumped in the car with only what we were wearing and drove to California.Long story short, we eventually ditched him when god was telling him that my mom had been having sex with my youngest brother and he was trying to figure out a good way to kill her as punishment. He spent a few days in a mental institution. We thought it was just a mental breakdown and life went on.
Apparently, demons had always been talking to him but it wasn't for a few more years until he was diagnosed as a paranoid schizophrenic.
He had a study one time that also heard voices. Because of this she immediately thought she must be one of the annointed when she found out about the whole 144,000 thing.
There was also a guy that would occasionally show up at the meetings in Utah. He partook at the memorial. One time he put a gun down by his chair at a meeting. He was told he couldn't bring it anymore.
I've known some and heard about some commiting suicide. Seen a bunch of other weird behavior.
Overall I think the religion is a magnet for people with disorders. It tells them what they want to hear.
