Imagine experiencing pervasive and perpetual sensations of dread and shame, the sort of visceral response that you might have when your body reacts to a physical threat. Envision how distressing it would be if you experienced these exact same feelings after viewing yourself in a reflective surface or a photograph. Imagine what it might be like if your body was the source of extreme feelings of anger, disgust, anxiety, fear, and hopelessness. Try to visualize how it might be if viewing your outward appearance triggered a reaction usually associated with a perilous situation, and how disconcerting it would be if every time you looked at yourself you experienced primal feelings of terror. If you have not had such an experience, it is probably quite difficult to comprehend how it is possible to have such a reaction to one's own body. This, though, is the very tormenting reality for individuals who suffer from body dysmorphic disorder (BDD).
