The are many potential reasons for Social Anxiety, but for most tend to exaggerate enormously what other think of ourselves and the truth is, no one cares much. One single public smile does more for you social skills than talking for three hours. For me the cure was “age” or, better yet, wisdom. Now, if you are inpatient, there are things that you can do to accelerate the cure before that… do get expose, open the window blinds more often and enjoy the sun and wave hi if someone checks you out… Look for activities where you can excuse the talk level like biking.
