I don’t think there’s anything sadder than when two people are meant to be together and something intervenes.
Forget your personal tragedy. We are all bitched from the start and you especially have to hurt like hell before you can write seriously. But when you get the damned hurt use it—don’t cheat with it. Be as faithful to it as a scientist—but don’t think anything is of any importance because it happens to you or anyone belonging to you.
