I would say that you sound depressed. Being depressed can make you lose your appetite and not want to eat anything. I'd say it was an eating disorder if you PURPOSELY stopped yourself for eating OR you felt like you were accomplishing something by not eating. Eating disorders are about control. Not wanting to eat is a combination of physiologial and mental forces. Just my 2 cents. Either way, you may want to talk to your physician. Other than not eating, do you feel any other "unusual" symptoms?

By the way, I think your weight may be too low for your height....even if you have a very petite frame.

All the best,
