“I know I should be happy. I should feel relieved. Lucky. We are lucky. So incredibly lucky. I know that. I know there are mothers everywhere, all over this country, all over this world, who would give anything to trade places with me. Who would love the chance to cry because they’re worried about their sons. There are mothers lost in the wilds of their own grief, who miss the days of worrying. I know. I know worrying is far better than grieving. But, God help me, sometimes I don’t know the difference. I can’t separate the grief from the worry.”
