Chrissy M Asked: my best friend isn’t eating. shes starving herself. 70lbs in 6 months. what can i do to help?

she always used to be the happiest person in the world. nothing bothered her. but since the beginning of last summer shes been secretly hating herself (i read her Tumblr). she was a bit over weight, but that never stopped her. I feel her feelings may have come from jealousy of her older sister. shes skinnier and her parents let her do what ever she wants and never seem to yell at her. its obvious she gets more attention than my friend. also, she jus had her cousin move in. she now also is getting more attention than her. Also, since my friend got a tumblr, shes gone a bit crazy. seeing all these pretty skinny girls on her dashboard (making her want to be one); while also seeing these girls talk about their anorexia (making her want to do it). Also, jus over the summer, 2 skinny girls in our school became anorexic and got EXTREEMLY skinny (which made her realize she could do it too and thought that their problems would be her benefit since she was already over weight). So now she wants to get skinny. infact already has. shes lost 70 pounds in jus a few months . im scared, but in mad. she knows she could have jus exorcized more and ate healthy, thats jus how our other best friend lost some weight. Also, i can tell she enjoys the attention of it WAY too much. her tumblr has turned into a total anorexic blog. all she blogs about is how she hates herself for being fat and how shes throwing up, running till shes about to pass out, and never eating. Her explanation of herself next to her name is just her eating disorder. and she loves to drop little dramatic clues in class like, my nails are turning blue, my hairs falling out. we ask her to come over. she says she cant. we ask why? she like, i have reasons….. . idk. you jus have to witness it
My friends an i had a sleep over with her one night and finally talked to her about it. for like 5 hours. infact we all even cried together about it. we miss HER so much. i have never been so sincere. It felt like wed finally gotten thru to her and were on the same page. sure enough, next day she changes faces and continues her little dramatic woah as me anorexic story on tumblr and posts about her her friends think shes fat. she KNOWS we didn say ANYTHING near that. Ive never been so offended. she jus loves ppl feeling bad for her.
Also, i know she dosent have an opposal to food. as much as she wants to pretend to to convince ppl, i know she still loves food. she still says things like, oh that sounds good, or looks good, or your mom needs to make those brownies again soon. she just hates fat, and forces herself to starve herself and over exorcise and when she doesnt she starves herself more to make up for it or runs more. she also once posted that she didnt know whether she should start eating healthy now and maintain weight or continue to starve and lose weight. THATS proof that she IS in control and ISNT trapped by a disorder. she jus choses to keep losing weight unhealthy.
Not to be mean, but she has always honestly been a bit lazy and impatient, and i believe that plays into this. instead of chosing to work hard and find health foods and work out a good exorcize schedule she jus said f*ck it im not eating. also she didnt want it to take long. she wanted to get skinny NOW. but all that gave her was flabby skin and ALOT of other problems.
~she also seems very depressed now. she went into this wanting to be skinny, thinking that would make her happy, but obviously she NEVER been so sad. I can tell tho, when she wants to have fun, & for example, join in on the dance party, but holds herself back on purpose. i can also tell that when she wants to have fun, and is in the mood for it, shes scared to, cause she doesnt want to look like everythings okay. shell feel like shes lieing to those she told she was anorexic by going out and having fun. she knows ppl dont connect anorexics to people who are fun and out going. but this makes me sad. i dont want her to feel like she has to keep up this reputation even when she doesnt want to.
So… weve gave her all the sympathy we could. all she did was twist our words. Weve told her to eat. all she did was sit there and thrive off the attention of everyon around her worrying about her. STILL she wont eat. shes nothing more than a girl full of deflated flabby skin anymore and shes still not pleased and thinks she ugly. Also she keeps pushing her only best friends away, and its getting really hard (and annoying) to keep pulling her back in. Im scared, and want to help her. Im also angry, but i dont want to blow up at her. im so confused. sry that was a lot but i think the back story will help you be able to help me better. i know she can stop, jus how do i convince her to finally do it? maybe youll be my miracle & be able to help me help her out!
GOD BLESS YOU FOR READING ALL THIS and for helping out a random confused teen who you dont even know just out of the kindness of your heart. thankyou so much <3
