I have been starving myself for a year now.. I felt fine up until recently. The past week I feel like I'm going to throw up. One day, my body did try and throw up but there was nothing to throw up.. this concerned me so I tried to eat but it's so hard.. I'm hungry but my body isn't used to food anymore and now I can't eat unless I force myself. My body is disgusted by food... at this stage in anorexia, what should I be concerned about?
