Zionistforever, I'm so sorry to hear about how these disgusting pigs are bullying you. I agree with the others that you tell the principal, and that you should have your parents consult a lawyer. The threat of a lawsuit should get the principal to do something.
Also, this might sound like kooky idea, but why not trying calling up your local chapter of the ACLU. Sometimes they actually help good people. Tell them that you are being harassed because of your religion, and that the school is doing nothing to protect you. Who knows? They might actually sue the school on your behalf as well.
Or if you let us know where in New Jersey your school is, maybe I can call them ask if that's something they can help you with.
And I agree with the others here that you should take a self defense course. Also, get yourself over to the gym, and start lifting weights. If anything you'll be able to move around with more confidence knowing that you are strong, and that you can defend yourself.
Let me know if you want me to call the ACLU for you.
