I'm not anorexic or anything, but for me, when I got really depressed I stopped eating for awhile. But then I would get insanely hungry and binge. You need to space out the food over some time and eat things that are healthy. Whenever I eat healthier things as opposed to fried, greasy, etc. stuff, I always feel better. You can still eat the same amount of calories and nutritional value, but with vegetables and fruits that agree with you
