Is this considered an eating disorder?

It doesn’t sound like an eating disorder to me, and under the circumstances, it sounds like you are coping really well. It does sound to me like you are probably eating less than you should be at your age, but a lot depends upon your current height and weight as well as how active you are (how much exercise you get and how much “manual labour” you are doing ). With regard to harleythecreator’s post: 1200 calories sounds too low to me, but there is a recognized method ( the Harris-Benedict formula) used to calculate the calories your body needs to supply your current basal metabolic life processes or “basal metabolic rate” (BMR):

BMR = 655.1 + ( 9.563 x weight in kg ) + ( 1.850 x height in cm ) - ( 4.676 x age in years )

Using that formula, a 17 year old young woman of average height (163cm) and weight (56kg) would require 1416 kCal daily to maintain basic life functions without losing weight, even if she was lying around in bed all day doing nothing. It is usual to recommend that the BMR is multiplied by 1.2 for people with a “sedentary” but otherwise normal lifestyle with negligible exercise (this would be around 1700 kCal daily). I can give the detailed recommended figures for other more energetic lifestyles, e.g. for an average height/weight 17 year old girl who is participating in moderate exercise 3 to 5 days per week the figure is around 2000kCal to maintain current body weight without risking health through lack of nutrients.

Hard to say. Your breakfast is definitely inadequate. You should be having three moderate-sized meals (not snacks) a day. That means not skipping lunch, too. What does “some veggies” mean? You can eat an awful lot of most veggies without getting too many calories, and that would do wonders for your nutritional intake. Try a really big salad for lunch, or a one-pound package of your favorite (non-starchy) frozen veggies, nuked. “half of watever my parents make me for dinner” - What do they make for you?
