Hi. The first thing that you need to understand is that you are very distressed and you surely need to see a doctor. In case if you don't have enough money to see a doctor, you should try contacting a state sponsored health facility. Treatment for anorexia
is generally long and involves both drugs and intensive psychotherapy
. initially you need to get admitted and increase your appetite. You can start with some where around 1500 Cal/day and gradually increase. If your tummy hurts, you can take liquid food instead. Neglecting this condition can be dangerous.
