Why do I get tense on small social gatherings?

Name: MeeraDate of Birth: 7th March 1998Place of Birth: JaipurTime of Birth: 6:50 AMThe minimal number of meetings are uncomfortable to me. My hands are trembling, my thoughts are running and I am unable to concentrate. I never thought in astrology, but I wonder whether this can make me clarify why my mental reaction can behave in this manner. I would like some tips to be less anxious and nervous in social practices.
