I feel the same as you. I have no clue how I got this bad. I've never been so obsessed with weight/food before...I just don't know how to take it. I will tell you something that I have been told many, many times. "You need food to survive." Going under 1,200 calories isn't healthy. That is the bare minimum people are supposed to eat. I know from experience that going prolonged periods with eating less than that amount really does affect your health. I usually get dizzy, start blacking out a bit, I get shaky, and I get really tired and irritable. Its not a road you want to go down. It seems like you are early enough that you can nip it in the bud... so try your best to do so!

One thing that does help is writing, or doing something artistic to channel your feelings in a healthier way. It really helps me, but I definitely agree with miguelsmom... delete those threads... they do nothing but feed your eating disorder. I hope things start to turn around for you soon!
