im a girl who's in middle school and i hang out with this girl. she's in my 3rd period and i sit with her at lunch. i don't feel like she's bullying me i would call it ' harsh teasing ' she calls me names and abuses my stuff. she one time asked to use my mirror to brush my hair then after she was done using it she chucked it on the ground and it broke. i was really upset but she didn't seem guilty at all and didn't even say sorry. she just said i could get another one at five below. she likes to throw my lunch box on the ground and it gets dirty. my mom yells at me for making my lunch box dirty even though i said it was my friend's fault and i told her to stop. i tell my friend to stop all the time but she ignores me. what should i do? she's basically the only person im actually friends with in 3rd period.
