Anorexia Recovery & Treatment

I’m a 13 year old boy and am trying to recover from anorexia. I am currently 5′6 and 83lbs (down from 120). I want to gain some weight back because my doctor threatened to place me back in the E.R if I do not become healthier. I was wondering if I do eat regularly will I get to a ideal weight for my height then stop gaining and pretty much stay there?

How long does it take to gain weight for anorexia?
if I ate 1200 to start to recover from anorexia how much weight can i gain in a week.

What happens if i just ate proper one day will that make me gain weight?

Ok, so i am in this partial hospitalization program for anorexia recovery. Right now, i am 5′4, 17 years old and 81lbs (i gained a pound this week! which is good, i guess). Anyways, the doctors there want me to reach around 100-105lbs and they see this as an ideal weight. However, i have always been very thin (i have never weighed over 87lbs– i continued to grow in height, but failed to gain weight). The idea of weighing 100 lbs really kind of scares me, but i want to get out of this program so i can go back to school and have my normal life again. I also know in my heart that i need to gain weight, but 20lbs seems like so much. Is 100-105 still thin for my height and age? The idea of gaining 20lbs scares me, and im afraid i will look and feel totally different. I am just really dreading it, because the doctors expect me to gain 1-3lbs a week, (they give you meal plans and calorie increases, but it seems like some of the girls in the program have to eat a ridiculous amount of food) or i will have to go inpatient. Can anyone help me calm down? I’m feeling really anxious and uneasy about all this

I am beginning recovery from anorexia (17 years old, 5′4 an 82lbs) and i need to gain at least 10lbs to stay out of inpatient. I am really scared, but realize that i need to do this for my health.
I currently eat around 1600 calories, but i need to boost that number. Would it be ok if i ate my regular meals/snacks, and supplemented with 2 Carnation Instant Breakfasts (230 calories each) and one Ensure drink (350 calories) a day? I’m scared because i know these drinks are kind of high in sugar, but i find it hard to actually eat more. So is this a good plan? Would it help me gain weight healthily, and does it affect where i gain the weight?
And also, is it good to drink a Carnation Instant breakfast made with skim milk after workouts? (Especially if i would like to gain muscle)
Thanks in advance
