Immature kisd (part 2)?

I posted something on here Monday because I was very upset when it hjappened and it happened again. I am a mixed African American and I don't get relaxers and my hair is natrually curly most of the time. People kept ooon talking about my hair or whatever because I always wore it in a a a fro or a curly style and I was sort of getting tired of it so I flat ironed it and curled it Monday and Today as well and today, I walked in homeroom adn there's this huge girl, she has to be like 220ish? and she hangs with the "cool kisd " or whatever, she laughed at my hair Monday and today ( I didn't go to homeroom yesterday to avoid hitting her in her face like I really really really really wanted to ..but I ignored her.) SShe looks like a big, and she's worn her hair in a damaged opnytail every since they were in middle school and it pisses me off that all she dose is talk abouit people like she's perfect.It wasn't only her, it was another girl who hardly has any hair aas well. When I walked in, she looked at me then rolled her eyes at me or whatever and then like 10 mins later, she started takling about me.Same with her "little friends"all of them have something bad to say about it but other people don't. Why do they keep on "talking" about me ? It's annoying. I don't even bother anyone and she asked me to see my notes from Honors English II cl cux we're in the same cl, i'm not going to let her see them because she always is talkinga about me. Am I wrong for not letting her see them?
