I am unable to communicate with others freely. I hesitate to talk with any one also I doubt to speak. My childhood environment made me coward and I always think in negative manner and feel doubt that something is going to happen to me though it is not going to happen I always think my self to get rid of this type of thoughts but no progress at all. Please suggest me how to mingle with others freely and develop positive thinking and kick out my hesitation and coward ness.
