What is Social Anxiety Disorder?
People with Social Phobia or Social Anxiety Disorder (SAD) experience considerable anxiety and fear when in social or performance situations, where the person is exposed to unfamiliar people or they fear being scrutinised and judged by others, and they often avoid social interactions.

People with SAD fear acting in a way that they believe will be embarrassing or humiliating or that may reveal physical signs of anxiety (e.g. sweating, blushing)
