More rarely it may involve a fear of using a public restroom, eating out, talking on the phone, or writing in the presence of other people, such as when signing a check. Although this disorder is often thought of as shyness, the two are not the same. Shy people can be very uneasy around others, but they don't experience the extreme anxiety in anticipating a social situation, and they don't necessarily avoid circumstances that make them feel self-conscious. In contrast, people with social phobia aren't necessarily shy at all. They can be completely at ease with people most of the time, but particular situations, such as walking down an aisle in public or making a speech, can give them intense anxiety.
Social phobia disrupts normal life, interfering with career or social relationships.
For example, a worker can turn down a job promotion because he can' t give public presentations. The dread of a social event can begin weeks in advance, and symptoms can be quite debilitating. People with social phobia are aware that their feelings are irrational. Still, they experience a great deal of dread before facing the feared situation, and they may go out of their way to avoid it. Even if they manage to confront what they fear, they usually feel very anxious beforehand and are intensely uncomfortable throughout.
