People with social phobia have a persistent, intense, and chronic fear of being watched or judged by others. They can appear as extremely shy or aloof. They are in constant fear of being embarrassed or humiliated by their own actions. This fear may be so severe that it interferes with work or school, and everyday social events. Physical symptoms often accompany the intense anxiety of social phobia and include blushing, profuse sweating, trembling, nausea, and difficulty talking.
People with social phobia can usually interact easily with family and a few close friends. But meeting new people, talking in a group, or speaking in public can cause extreme anxiety.
