Hey... I'm 13 and I go through the same stuff.
Well, you guys may think this is bad, but having cf caused me to not be religious at all. The way I see it, is that if there was a god, then he wouldn't cause these types of things to happen to people... but if he had no way to stop it from happening, he would still "magically" make it disappear.
Like i said, you may think that is bad of me, but hey... I can believe what I want, and you can believe what you want... and lets just leave it at that.
