Why do I feel nervous during random meetings?

Even informal gatherings cause me to be nervous. My heart grows fast, I squirm, and think myself to pieces. I have not used any of the astrology ingang, though I am left wondering whether it can account for my reasons behind this feeling and lead me into self-confidence and nostra gentes in social life.
