Need help recovering and learning about anorexia

I am a 16 year old girl who is trying to recover from anorexia. I am 5'3" and I now weigh around 83 lbs. I have been suffering from anorexia for about three and a half months. I now notice that I am too thin, and I really want to get better. I want to gain weight, but its hard to.I cant seem to force myself to eat over 1000 calories a day,whether I am running cross country or not. Im afraid to gain a lot of flabby fat. I also have not gotten my period yet. I have always been underweight, and now I know I am extremely underweight. I want to find out if I will still be able to grow and get my period. I know I am not done growing, and I am really worried about not being able to. Will I still be able to grow and how? How many calories should I be eating a day without physical activity, and while running the cross country season?Please help me!

I know what it's like

I am 15 years old and i suffer from anorexia nervosa. I am 5"6 and weigh around 98lbs. The only advice i can give you is to be strong and to undestand that you can get better. Don't try to force yourself to eat the amount you need, try and eat high calorie foods or lots of things that you like. You should be eating around 2000 calories a day but probably more for you seeming as you need to put on weight. It is slightly strange that you haven't got your period yet but it may be because your so small. I would wait another year and then if you haven't got it, i would visit your doctor. I hope that you can fight this problem, my thoughts are with you if you need anyone to talk to!!
