Im getting accused of copying when im not?

So this really stuck up b*tch who treats everyone like crap if its not her way its the highway, so i shared an interest in some things she got, and i wanted to get them but they werent gonna be the same, so she starts at me saying i cant find my own style, and i dont dress anything like her, i sometimes tease her saying ill get the same but shes so stuck up her own ass she doesnt understand a joke, and now after this whole argument, im scared to go to school because of what she might stir in people brains ad everytime she posts a foto its her saying something like atleast i have my own style truth is she doesnt she copies me alot, making it look like she wanted it first, what can i do? Im just so scared, do you think shes being childish, cuz my friends sure do and im 16 btw
I think its you that sounds like a 7 year old throwing stupid punctuation insults, this isnt a english session.
