I used to be religious and can say prayer as a coping mechanism is priceless. But I too found too many unanswered ambiguities and lost my faith in its real world application.
I would give anything to have it back now, just so I could pray, and believe things were going to be better, like I used to. It was invaluable. There was always someone who loved you, no matter what, and cared about you, and you knew was fighting on your behalf. But you can't put the toothpaste back in the tube.
