I find it increidiby hard to believe there's a God when in the same year a friend and my cousin had a brain tumor, and my parents divorced. My friend is well now, but my cousin isn't doing well at all, and last month he had a seizure and doctors couldn't do anything for him at all. He was only supposed to live a day or two.
And now, a month later, he's still alive. But I think when things like that happen it definitely lowers your amount of faith in Him. I've been brought up to believe in organized Reigion, going to Mass every Sunday and Holy Day (of obligation - even Thanksgiving which isn't a Holy Day but damn well should be) with Christ, God, and the Holy Spirit, so that's what I'm going to do from now until . . . Who knows when.
