Am I dealing with disordered eating? • • • Do you spend time wishing parts of your body looked different? Are you unhappy with your reflection in the mirror? Do you skip meals? Do you count the calories or fat grams in anything you eat? Do you exercise so much that you are fatigued? Do you weigh yourself often and find yourself obsessed with the number on the scale? • Are you afraid of gaining weight?
