BDD is a somatoform disorder. People with BDD may look at themselves in the mirror too much, or some people with BDD may actually try not to look in the mirror. Both of these are possible for a person with BDD. They usually think about their body for more than one hour per day, and in bad cases, can stop talking to other people, and may stay at home. People with BDD often have very low self-confidence, because they believe that a person's value is linked to what they look like, and because they do not think that they are beautiful themselves, they do not think they have much value.
