Ever since I was little from 8 I've been skinny not realising I'm under weight I'm 18 now and found out I'm anorexic I eat but only a little bit I'm afraid of getting fat I've only put a tiny bit of weight on but I keep losing it because I walk to much and exercise 2 much I don't even know how to keep weight I put on ect I like being skinny but people keep complaining about my weight and it annoys me my periods haven't stopped so I'm not 2 skinny any help?
