Maybe see what they are wearing and try buying stuff like that style. Or try making friends with some of them and then they won't judge because you will become part of their bff bubble. Or just be yourself and eventually they will see you for who you are and you will fit in easily. Maybe you and a friend could try sitting on the same table as them every lunch and start joining their conversations to communicate with them. Or try saying the stuff they say and trying to be cool around them. And maybe if you start making friends with boys and start being cool around them you might get a boyfriend!
Just trying to help a fellow kidzsearcher out!
