My 30 year old sister had a partial hysterectomy approx a year ago.  Her personality has completely changed, she went from moderately self absorbed, caring and loving and even tempered and centered to aggressive, reckless and totally narcisitic.  We no longer recognize her.  Ciuld this be related?? How can we recover our sweet girl???? We need a specific course of actioin because she thinks we are all jealous and out to get her...
