People are individuals and there's no way a parent, just a normal, unsuspecting/untrained "adult" can know what a child, even their own child, may "need" and how to teach that to that new person. Parents are not all-wise or all-good/unselfish and have their own lives to live; feeling one's parents did not love/teach one enough is one's own perspective, not necessarily "Truth". My personal quirks got in the way of my initial learning growing up as did my mother's illness and death when I was a toddler, my stepmother's failing at not being my real mother, etc. It's not our parents fault we go to therapy; it's (hopefully) something we have decided to do because we think it might help us better understand ourselves and our lives and those around us. For me, therapy was a learning experience and I enjoy learning, even when the lesson is difficult. All's well that ends well; it's just Life.
