For the family, it's tragic, and I can't imagine such a devastating loss. To know that her love for her daughter was so strong, though, that the loss literally killed her. I don't know. As a testament to the human condition, though, I could only hope to feel so deeply for someone else.
Seems to affirm the idea that people do have a 6th sense of sorts. Kind of like those stories you hear about a husband and wife who die hours apart from one another.
