Why is my wife fussy at the family functions?

My wife is apprehensive and nervous at family gatherings. She does not socialize and appears to be stressful even with people who she knows well. She became unsatisfied with social self-help methods and meditation. I mentioned that astrology could be the reason behind her responses. We wish that it could lead her to being more assured and relaxed when around other people.
