Struggling with pre teen

Yess! My pre-teen daughter 11(soon to be 12) and she is also type 1 diabetic so her hormones literally affect her sugars 🤦🏽‍♀️ her attitude atm is driving me crazy

What kind of behaviors does she have some times mine is the most adorable then she goes from 0-100 she did get bullied at school previously

Her attitude is my biggest irritant atm but the talking back,not listening and just sometimes having to tell her to do everything like tidy her room,have a shower ect. She can be the sweetest and kindest but can just go from 0-100
