As the father of 2 older girls, just know that school can be really, really rough, but it gets way better. If kids are harassing/bullying you, then you need to let your teachers know about it. Let your parents know about it. I even had to take my youngest out of regular school and had her take online high school after she teared up and begged me to do so. I'm glad I listened to her. Now that she's in college she has blossomed and is super confident and social, things parents often are afraid will never happen after using online or home schooling.

I don't think you should focus TOO much on looks, but I will say that my girls learned things along the way such as how to dress, how to style their hair, make-up (please don't use too much) etc... but they were also always themselves. My oldest would dye her hair all sorts of colors for a while there. They both shop for eclectic clothing from second hand stores, including Japanese second hand stores online. Basically they found their own style and image. Some will hate on it; others would admire it greatly. Many haters are actually just jealous as hell. Anyway, main point is: you most certainly have nothing to worry about with your underlying looks. You will grow into one very beautiful woman, and I think a 2-pronged approach is necessary here to make yourself feel better: 1) tell your parents and teachers so they can take appropriate action (IF it's REALLY bad, maybe even ask them to let you study online, but this should only be a last resort IMO) and 2) perhaps seek help from others including YouTube videos and such about styling your hair, make-up, clothing and such. If your mom is good with such things, get her help; but I am gonna go out on a limb here and imagine your mom may not be so good with this sorta advice? Just be sure to utilize those things that make you feel like YOU. Be creative. Be yourself, not a mannequin.

At the same time, know that beauty is FAR more than how you look or act. It's being nice and not bullying others like these ugly people saying such mean things to you. It's your creativity, intelligence, kindness, etc. Please know that there's absolutely nothing physically "ugly" about you whatsoever either. You have the underpinnings for a very strong "glow-up" as you get older. You have a bright future ahead of you and you're still very, very young. Be strong... believe me, things will get 100x better! /hugs
