How to overcome the fear of facing the crowd?

Hi, I have been suffering from social anxiety and it is ruining my life. I am scared to face people from my childhood. I become very scared and anxious when I have to face a huge crowd. I even act weird in front of my family members. I think that it will cause big troubles in my future life and has decided to undergo anxiety disorders treatment ( http://www.cbtassociates.com/about-you/problems-addressed/social-anxiety... ) from Toronto. Is there anybody over here who also suffer from social anxiety? What all things do you do in order to keep that under control? Please give some genuine replies and suggestions.
