I feel like everyone is judging me constantly?

Maybe you put out an image they are not familiar with, confidence. The others may not be familiar with what you are and instead of learning from you they want to bring you down to where they are. I am sure you are not the only one in your school who is singled out, find some one who is also singled out and become friends with them. They will need a friend as do you, and you can build from there. I hope this helps you. Be confident and let their glares roll off you, after a while they will give up. Kill them with kindness and be polite. Be who you are, and try to become the person you want to be.
