Just to give you an example I am 23, 5'3" and weigh 196. If I wanted to MAINTAIN this weight I could eat 2176 calories a day and not gain an ounce.
What I would suggest is to find a good basal metabolism calculator and it will ask for your age, height, weight and gender. It will then calculate how many calories you can eat to maintain your current weight. Then depending on if you want to lose or gain weight add or subtract calories. It takes a defecit of 3500 calories to equal one pound of weight loss which is 500 calories a day if you break it up over 7 days. The same could be said that a surplus of 3500 calories will cause you to gain one pound (not counting water weight, that is a whole different monster).
"Normal" eating is eating when you are hungry. Have a well balanced meal, something you like, just watch the portion sizes.
Good luck with your continued recovery!
