Body dysmorphic disorder is a chronic mental illness that causes you to constantly obsess over a perceived flaw with your appearance. This disorder is most common in females. This flaw is either imagined or very insignificant. This flaw or imagined flaw is not apparent to anyone else; usually because it doesn’t exist. This disorder makes you feel ugly and ashamed of. When you have this disorder you obsess over your perceived flaw for several hours throughout the day. Some will get plastic surgery to "fix" the problem they see. However, many will just find another flaw to obsess over. Some symptoms that may indicate body dysmorphic disorder are: preoccupation with your appearance, a continuously strong belief that you have an abnormality that makes you ugly, frequent cosmetic procedures with little satisfaction, and the need to wear excessive clothing and makeup to cover up perceived flaws. Many will obsess over a particular body part such as the nose, skin, or hair.
