C.s. Lewis said this quote

For in grief nothing stays put. One keeps on emerging from a phase, but it always recurs. Round and round. Everything repeats. Am I going in circles, or dare I hope I am on a spiral?But if a spiral, am I going up or down it?How often -- will it be for always? -- how often will the vast emptiness astonish me like a complete novelty and make me say, I never realized my loss till this moment? The same leg is cut off time after time.
