Copycat friend (?)

Hey guys, so i have this friend and it just seems like everything i do she will do it later, maybe she’s not copying me but it’s kind of annoying that she cannot be her own self, she repeats everything i say, if i do something i’ll catch her doing it later too, my clothes she always tries to dress like me she’s such a cool girl when she is herself and I understand we might have things in common but its just getting annoying that I can’t have my own style w/o someone copying me. Have you guys ever had someone copying you?
