Social Anxiety Disorder (SAD) is a social phobia which is caused due to many reasons. It is the inability of the person to mix up with the surrounding people.
SAD is the most common psychiatric problem faced by the 12% of Americans in their life time. It causes a considerable distress and sudden weak and dizzy feeling when coming in contact with the crowd.
People experience this mostly at times when they have to eat or drink in front of others, working in front of people, being a focus of attention and talking on phone.
This disorder is not serious but depresses the person hence treatment is necessary for it.
