Yh i used to be anerexic?

Well, first off congrats on beating anorexia. What I would suggest is eat 1700 calories a day and try to go to the gym for an hour 5 days a week, but take off on the weekends from the gym. The way I see it, you are eating just under what you BMR would be, which by the way is the number of calories a day your body burns naturally. That way, you would lose weight, it would not be under the daily limited calories your body needs, and it would not be too rapid of weight loss...all healthy. If at first you gain a little weight, just remember that it's all muscle and it weighs more than fat. At the gym I would suggest a slow pace on the machines and low impact machines. Make sure you weigh yourself weekly so that you know you aren't losing too much weight. I wouldn't suggest losing weight because you could relapse, but if your mom thinks it would be okay, then go for it. Just make sure your mom watches you so you don't relapse and go over the top. Try low fat foods and if you get hungry for a snack really late at night or when you are in school and can't eat, chew sugar free gum. It helps distract you from your hunger and you burn off the calories in the gum just by chewing it. Good Luck!
