My personal experience is consistent with your second point.

But I'd be careful about making conclusions from the suicide/antidepressant statistics. It's shown to be highly correlated to altitude. I've included a couple links from google search to demonstrate the point.

That being said, the Mormon/LDS church does cause some psychological hardships for certain groups such as LGBT and ex-mormons... at least in my anecdotal experience.
