Elizabeth says her youngest children, Jack and Emma Claire, know more about her diagnosis than she tells them.
"I tell them I have this disease, that this disease is what will probably kill me," she says. "[I say]: 'I happen to know what I'm going to die from. You all don't know yet, but everybody's going to die. Everybody's end is the same.'"
Since burying her firstborn, Wade, Elizabeth says death looks different. "It's not as frightening," she says. "It is a relief. I mean, that's my expectation, but I don't think it takes all the fear away."
