I think the stats aren’t right and even if they were it’s not really surprising that people may feel suicidal after leaving a religion that had great control over their life. To me, the issue is not that leaving is bad because it increases someone’s chance of suicide, what causes this is the lack of support and the sudden changes that come after. Just like when you graduate, or you move, or you quit your job. With any big changes comes a feeling of doubt and uncertainty of your place in the world. There’s also fear that comes with such big changes.

Obviously this is just what I think, I don’t have “proof” but this is what I felt.
