Yes you can be anorexic without counting calories. I am in recovery for anorexia and I never once counted calories. I am about as tall as you and weighed x lbs and was put inpatient and almost had to have a feeding tube because my weight was so low. I am now at a healthy weight and have been for 18 months. I also never lost my cycle. Whoever told you that you can't be anorexic is dead wrong. You want to catch this deadly disease before it gets any worse. Being hospitalized is no fun at any age, let alone school aged. You miss out on friend's birthdays, holidays, school, etc. For me I missed out on my daughter's dance recital. That is something I still regret to this day. I have been fighting this disease for 18yrs and I am only 33. Please get help before you do irreversible damage to your body.
