Why is religion so confusing and complicated?

I am a Catholic, and I truly love the faith, but I get where you're coming from. Doubt it entirely natural. The complete truth is that nobody KNOWS with complete certainty what is real. It's becoming increasingly difficult to stay strong in faith with atheism becoming the new "in" thing. I encourage you to pray a lot, and find yourself a solid community of friends who share your beliefs, and maybe even your doubts. Good luck.
