Health or Weight?

It'slightly embarrassing to admit that since my last post i hadn't thrown up or starved myself, first because i had to keep myself conscious, and then because my school was on camp and i couldn't do anything but it's okay because i was losing weight anyway..
Well that was the case until yesterday when i threw up again for the first time in 2 weeks & it felt like all the tension that had built up from those weeks just washed away...
Today I was back on track with my starve plan but -i can't believe it- i nearly passed out again!
This is so ridiculously frustrating because normally my body is a lot stronger than this... and i knw this means i'll never be able to diet like this again.
I have to say i'm slightly scared about what i've done to myself, apparently there's a good chance that im anemic and besides that, my hair has been falling out.... i'm not sure if it's an effect of events of this past yearr or something else but im starting to get more and more worried about what's happening to me
still, i can't make the choice of whether to keep myself healthy or get skinny...
