Allow me to speak from experience... My mother, while clearly significantly ill, kept her health trouble a secret from our entire family. It affected us a great deal as we became frustrated and even resentful of her unwillingness to be open. I didn't press her for information; I respected her wishes that she keep her condition private. Yet, the frustration pushed us all away from her. I wish she had shared whatever her health situation was. I'm sure we would have remained close to the end. There is another very serious reason it would have been important for her to have shared. Her health history may have proven valuable to myself and next generations. I am now the age she was when she first got ill and starting to face my own troubles. I am being asked about family health history and am at a loss to provide any.
