Publicly, Marie has put on a brave face, but privately, it's been a much tougher struggle than she's let on—something her brother Donny has witnessed firsthand.

Marie says that in an effort to comfort her and help her get past the grief, some people have said unintentionally hurtful things. "I've had people say things like, 'Well, at least you have seven more children,'" she says. "I'm sure they're trying, but no, I have eight children."
Other people's words have given Marie great comfort—particularly when other grieving parents tell her that, "No, it does not get easier." "That makes sense to me because it doesn't [get easier]," she says. "[Instead], God gives you little respites."
