Your evidence of believers in your religion coping better than all others appears to be anecdotal. Are there any statistical comparisons that support your position, for instance, of comparative mental health, or self-image?
This isn't going to help a lot but I read about some studies a few months ago supporting this. Those with religious belief are, it seems, "happier" than those without.
I think it was an article in "New Scientist".
I remember little about it beyond that.
