My friends an emo poser.?.?.?.?.?

okay so like my friend is totally NOT emo but she thinks she is shes all like "god, i am just so f*cked up right now" and she cuts herself for attention cus shell cut herself then come to school and like be all showing them off. i mean what should i tell her ive already told her that she needs to stop focussing on herself and start thinking about those who have it WAY worse than her. i mean the only reason she went emo is because of this guy who im pretty sure is ALSO a emo poser. i mean but she is ALWAYS happy around me except when she is around other people she acts all emo and crap. wtfh. and i mean if shes really "emo" then shouldnt she like not admit to it? and whenever shes like "take all the sharp objects away from me" im all like "here ya go, i dare you" and se doesnt cut herself or anything. i mean she put a screwdriver to her stomach but i mean seriously, she wasnt even pressing it hard enuff to hurt. so yeahh what should i tell her?? thanks!
