I'm not religious and cope much better now then when I was religious. My wife who is religious copes better when she relies on my non-religious opinion. Humans when they give up religion find their place in life and don't rely on a superhuman being to rely on and depend on their own reasoning.
I am not religious, and I still manage to cope with life. It's not that difficult. People are just afraid to come out of their shells, theoretically speaking, religion is their protection.
