why is my friend trying to be like me?

[Josh]

It might sound stupid but its the truth. Im 13 shes just turned 14 the other day. Im in 8 grade we have been friends since 6 grade the first day of 6 grade. I liked her at first she was different from other people. Then in 8 grade she would ask me my fav. bands and i would answer: Asking alexandria, BVB, Botdf, three day grace, green day, 21 guns, and ect... then she would listen to the same music to me... i got really mad and mostly beacause she gets accepted better than me... everyone likes her better i dont know why. Them she would look through my Phone and have the same apps. I told her I would dye my hair and she went and dyed it! i tell her i go to hottopic to but clothes she goes buy clothes from there! I just cant stand it anymore... she says she looks up to me... but shes being like me. I started cutting myself i have too many problems at home, she starts cutting for no reason! I stoped eating so i could be skinny beacuse my OWN FAMILY WOULD MAKES FUN OF ME ): i was 110Lbs and now im 100lbs... then she stoped eating. I read a book she reads it.
Can anyone tell me what to do please? I reached my limit... i cant stand it anymore... ]: I just cant...
Also im a girl but my nickname is josh my real name is jocelyn... im a tomboy, and then my "friend" got ride of the make up she had and pink... Ive had many people over the years trying to copy me but this is over the limit... help anyone?

She admires you. It's like your her role model. Tell her how you feel.

I don't really know if you're this type but, tell that b!tch off! If you're not...simply tell her you're doing crazy sh!t and she'll do it. Everyone will hate her then go back to being you. By then, it'll be too late for her to change.

well to be honest it sounds like shes becoming a poser or it could simply be she acts like you to be closer to your friends that act like you or she like someone who likes that music ive been threw the same problem with my friend trayvon where he liked a girl so he said he would listen to what me and my group of friends listen to just to be closer to her than at lunch last year(8th grade) i was listening to bvb than he asked me what band are you listening to and i said bvb and he said his favorite song by them was scream for my ice cream but thats a poser and if your friend acts like that than she might be a poser
