Going to bed hungry..

My mom made this Mexican beef rice tonight for dinner, I don't know the nutrition facts for it because it's homemade. I feel like it's not a healthy meal, so I only had a half cup of it, and that's all with nothing else on my plate. I'm hungry, but I feel like just that cup was around 400 calories, and if I eat anything else then I will go over my limit on fat, calories, and carbs. I wish I could enjoy food like everyone else, and not have to worry on how many calories,fat, or carbs are in food I'm eating..
