Please explain what are the beginning stages of an eating disorder?

Questions...: Are you underweight for your height, but think you are fat? Do you obsess about gaining weight ; think you are fat, although others tell you you are too thin. Have you stopped menstruating? Do you nibble at your food and throw most of it away? If you are worried, it is probably worth consulting with a therapist who specializes in anorexia. It is hard and; very important to take care of asap.
