Is it normal to be worried about food/eating all the time?
Ever since I was about 7 or 8 years old I can remember comparing myself to other girls to see if I was fat. I kept a diet diary for several years and weighed myself once a day or more. Recently I have been compulsively counting calories in an attempt to lose weight. I try to stay under 500 calories and I can manage to do so, but at times if I allow myself to eat one bite of something I fall into an uncontrollable binge...and I don't mean just a few extra bites, I truely Binge!!! (i.e. eating a whole box of cereal, or a whole bag of bagels, or entire boxes of granola bars, etc). Then the day after the binge (or even a few hours after the binge) I feel terribly guilty and depressed by my eating, sometimes to the point where I will break down and cry. Lately food has been all that consumes my day. I spent HOURS upon end on the internet reading about diets, looking at thinspiration videos on youtube, and looking up the amount of calories in certain foods. I also often plan what I can eat for the next day when I lay in bed at night. Then when I go to the grocery store I have a constant battle in my head with the amount of calories in certain foods and what I should allow myself to buy. I just feel like no matter where I go or what I do I am CONSTANTLY worrying about how fat I am, how I can keep on my diet, food I can or cannot eat, and calories.
Is this normal behavior?
