Friend problems? Would like a mom's advice?

From a Mom...Try to hang out with a whole new group. If these girls were really your friends, they would be trying to include you in their conversations and would not let you trail behind by yourself. They probably see you as a little insecure and teenage girls will pounce on you and tear you apart for that. Muster up all the confidence you have and go sit with a new group of people you kinda know but don't usually hang out with.
