I’m just not into it

I’m 13 and have never been interested in makeup. In high school it seems like all the girls wear it and i feel different for not being into it. I also feel insecure about myself as all these girls that wear makeup are soo pretty and I look like a potato. I have been bullied because I was too ugly, fat and had my own style .It also doesn’t help as I’m the only girl in my grade that does an aviation specialist class. I just want to fit in but it’s just difficult
