Hello doctor. Im 18 year old male. I have suffering from over shyness when i go outside from house. I always think about what other people are thinking about me and my look. Due to this, i was unable to walk or behave freely in the society. I cant behave freely as i behave in my home.  I always over think about how others talk and feel about me. Im having this from childhood. How to cure this and make me behave normal in society? Please suggest me some treatment. I want to behave cool and free among people.
