d suggest seeking help from a therapist, dietician, and psychiatrist. If you have
health insurance, often they can provide these resources at a low cost.
Until you can get help, eat a balanced diet from the food pyramid. You can even look up bulimia recovery meal plans. Eat consistently throughout the day, regarding food as fuel rather than a source of comfort or punishment. Focus both on calories AND macronutrients. 2000 calories is a good starting goal.
