Picture your worst fear or most shameful experience becoming associated with an area of your body, and then magnify this image many times over. Within the construct of body dysmorphic disorder, a body part takes on an identity of its own. The body area of concern becomes profoundly associated with the individual's sense of self: The individual with BDD misses the forest through the trees, and rather than seeing many different body parts that together shape outward appearance, the despised physical feature becomes the focal point of their existence. It can easily become the singular element within the person's life and a gauge that determines the entirety of their self-worth.
