Do your emotions give into bad eating habits?
Yes. When your emotional state is out of the average your more than likely to turn to food to help you. When your either feeling sad, angry or any other type of negative emotion you turn to food to comfort you because you know it wont reject you. Even with special occasions or birthdays or simply just parties their is always going to be some sort of food around.
