<human>: My little cousin is like a sister to me. I was raised an only child and lived in her household for a while growing up (my aunt is like a second mom). I suffered from a severe eating disorder from ages 9 to 21. When I was in the depth of it, anorexia had me down to 81 lbs at my lowest, And I am 5'9. My parents practically forced me into two treatment facilities in my teens, for fear I was close to death. I've had feeding tubes in me more times than I can count. When I was in this mindset no one could stop me or control my eating habits or behavior. It wasn't until I joined the military that my eating disorder was finally under control, as per necessity. 

She witnessed all of this. Her mother (my aunt) would send her as a child to beg me to gain weight. She is well aware of my struggles and I can't help but feel as if my problems influenced hers. When I was living there, she looked up to me and glorified everything I did. 

Now that she's having the same problem I don't know how to talk to her without coming across as hypocritical. She recently completed a treatment program that put my aunt into pretty bad debt, and I just got a text today from her best friend, telling me that she left school early because she was too weak to walk up the stairs. We are all scared for her. When I came back home on leave, she had lost significant weight since I left for boot camp. She was gaunt, and it's getting worse. 

I'm afraid that if this doesn't kill her, she will have to deal with the permanent physical and psychological damage that happened to me. I told this to her, and she replied that she simply cannot bring herself to care about her health or well-being. What can I do?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My 16 year old cousin is slowly killing herself due to a severe eating disorder, and I don't know how to talk to her about it because of my own past with anorexia.
