recovering from anorexia

hey everyone, i'm new here.


so i started starving myself when i was 15(i'm 19 now)and i got down to 80 pounds, i'm 5'1. i recovered on my own when i was 16 and i went a little overboard with eating, and got up to 135, so i was overweight. i had a boyfriend who i thought was good but he wanted me to be skinnier, so i started dieting. it was taking too long for me to drop the weight, so i started eating 300-500 calories a day. i still didn't look how he wanted me to look, so i started only eating rice. i got pretty sick, but only down to 100 pounds so i thought i was fine. that's only a little underweight for me. but i was pale, i had really low blood pressure(65/84), my hair was falling out, i was cold all the time, my body temperature was 96.3, and i now have hypoglycemia.

i didn't realize it was a problem until i caught a glance at myself in a window and i looked horribly bony. i have since gained 3 pounds and i am trying to eat more. but i've noticed since i started eating normally, 2 weeks ago, i am nauseous and i have been getting migraines and i'm not sleeping well. i'm wondering if that's happened to anyone else? i'm eating 1200-1400 calories a day now. my friend told me it's just my body getting used to food again and it's sort of rejecting all of the food i am feeding it. is that normal?
