I'm sure that the rewards were there, but perhaps not what she was expecting. I would not be surprised if some of her depression came after the age of 40. Women go through so much with menopause. I'm a little biased, because I am happily married and find this time of motherhood to be the most fulfilling. I don't think we should assume that Mother Theresa was ultimately different from any other woman who gives up family life for career (even if that career is as a world-renouned humanitarian), and becomes depressed when she gets older and realizes that she has not fulfilled her female drive to bear children.
BTW, even if all of this is interesting about Mother Theresa. It bothers me that this stuff is coming out against her wishes.
Just wanted to add, I’ve been to some of Mother Theresa’s homes in India. No matter what her personal feelings -or lack of feelings- she did something pretty remarkable there. Old people and young orphans and cared for. Poor children are given an education. Her popularity got assured that donations came in regularly. You can’t discount the good that came from her.
