Eating Disorders

How do you determine that you truly have an Eating Disorder? It took 30 years of complete and utter out of control eating and of the Dr. Oz show for me to realize it. I have struggle daily since I have obtained  the  label " Binge Eater". I am wondering if it I would have remain clueless of my disorder, would it really made a differnce. I started really montoring my food intake this week. Summer's coming and I have nothing that fits me. I refuse to buy new summer clothes.
