What do I do? Friend help? Please?

Ignore them all. I know it sounds stupid, but if you allow them to make you feel insecure, then you will be insecure. I know its hard not having anyone to talk to, I went down that road myself a long time ago. And if i had learned anything from it, it was my reactions that kept the cycle going. These people are not your friends. A real friend would stand by you and be there for you when you most need them. Diana wants to be part of the "in crowd" and that is not a friend. Maybe you should find something else to do, like maybe joining a youth group. Sometimes you can find your biggest supporters and kids who are going through the same things in youth groups. It can also help with your self esteem. Walk around like it doesn't bother you and show no emotion when these people start to act a fool. In reality, once HS is over, those people will cease to exist in your life and you can be free to be who you are without the worries of the he said she said bs. It will be hard but you can do it. I wish I could be more helpful with advice. The only thing I could offer is an ear for you. You can find me on FB and if you ever need someone to bend an ear from a rough day I am always up for listening, provided that its ok'd by your parents.
