You both missed the point. Although I can’t speak for all abandoned children, I suspect many would have the same or similar outlooks as me. I have an unassuaged anger toward her. Although I’ll never get answers, I yearn for them. She didn’t give me up for adoption. She just left me and my father, who promptly handed me off to one relative and caregiver after another until I was old enough to warehouse in an all girls Catholic boarding school. It was barely one step up from an orphanage and, if you’ve ever done any reading about how cold and cruel nuns could be to the children in their care, you’d know what my childhood was like. So I never wanted a relationship with my mother. I wanted answers and an outlet for my anger. I am an older woman now and she must be long gone, so it is what it is.
All I can say is be thankful for what you do have and build onto that. No one leads a perfect life. We all have our trials & tribulations. Some unfortunately have an excess of those trials & tribulations, and you have certainly had a considerable amount with your misfortune of having two parents who were not good parental material. Perhaps though it made you realize the importance of being a good parent and you turned out to be a great parent. Since I don't know your whole life story I can only hope that was the case.
Seek out God, as he is the best parent a man or woman can possess, and may he bless your days moving forward.
