BDD
Body Dysmorphic Disorder (BDD) is a disorder that causes a person to be excessively concerned with body image. A great example of this disorder is millionaire Jocelyn Wildenstein (pictured). She has reportedly spent over $4 Million on plastic surgery. From the looks of it, she should have left well enough alone.

Factitious Disorder is a bit like hypochondria. Hypochondriacs actually think they are sick, but people with Factitious Disorder lie about being sick for attention. They will sometimes harm themselves in order to gain attention. There is no cure for this disorder. This disorder is also referred to as Hospital Hopper Syndrome.
