My sister..

basically
my sister found out that I throw up after I eat
and that I have an eating disorder today.
apparently shes been really upset.
but before now I didnt think she cared about me.
this sounds selfish but
she hasnt asked once about me,
shes just getting all of the attnetion for being upset,
and im the hated one.
I dunno what to do
:S

Firstly, get help for your eating disorder. It might feel like a lot of stress getting the help but trust me - It's worth it.!

Secondly, you're not the hated one. Maybe your ssiter is getting the attention because she cares for you and wants you to be healthy.

Well your sister sounds like my brother! When he like rode over me on his bike he was crying because he felt bad and everyone was like awww he feels awful while I lay there bleeding. Have your parents and friends found out? Did your sister tell them? I make myself throw up too, and I dont want to go to one of those places. If you want to stop, if you can do it, then do it gradually. Eat small, healthier meals and try to keep it down. Obviously you will feel the need to make yourself sick sometimes, just do it less often.
Hope I helped

I don't know if you're the same anonymous poster who's question I just answered, but I'll repost my answer just in case you're a different poster.

You sound like you have an eating disorder such as anorexia and/or bulimia. You are not only attempting to fool them but you are fooling yourself. Anorexia is a killer. If you revert back to those negative habits you can quite likely permanently harm or even kill yourself. If you want to see what anorexia/bulimia can do, even in just two and a half months, take a look at my question and my answer at:
