Kookoo Bird,
I can understand what you are going through! Kids have a tendency to pick on people who are different from themselves. In a way it helps them over come their own insecurities. But don't worry too much about it. It will just make you a stronger person.
Another way to deal with it is to sort your own thoughts about this topic. What do you think about the topic of God and religion? Don't just blindly follow something because you were told to do so. Try to find your own answers. And keep an open mind while you try to find answers.
