I embarred myself in front of the school`s popular girl and her clique, what do I do?

Oh gosh >.<, kid, this girl and her friends do not matter. Trust me, things will change and sooner or later you will be laughing at yourself because you cared so much. I've been there. I've cared about popularity. Now I'm a senior in high school and I could care less about who the popular people are. None of that will matter when you're all grown up with a job and a family. You seem overly obessive, don't let them get to you. Just let them go and move on with your life.
