“I keep thinking grief feels like climbing a staircase while looking down,” she said. “You won’t forget where you’ve been, but you’ve got to keep rising. It all gets farther away, but it’s all still there. And you’ve only got one way to go and you don’t really want to go on rising, but you’ve got to. And that tightness in your chest doesn’t go away, but you somehow go on breathing that thinner, higher air. It’s like you grow a third lung. Like you’ve somehow gotten bigger when you thought you were only broken.”
