Apparently i'm not "cool" enough to hang out with people?

At my new school, no-one really wants to be my friends i think. They still talk to me though. If i head there way during recess/lucnh which i'm not. They will give a shock look and embaressed look as if they are to embaress to even say that i'm there friend. So now i hang out with girls that are a higher grade then me. They seem heaps nice, then after school i saw a girl from the group. She didn't seem she wanted to walk with me either. She was like aren't your friends that way? She pointed at the opposite direction of where she was going then she went straight up the escalators running up. I feel really ngelected. By nearly EVERYONE! It's really hurtful :( I want my old friends back. THey atleast care about my feelings. Sometimes i feel suicidle at that school. I've told my parents about this they didn't care. How can i convince my parents to move schools?
