" Happiness isn’t natural. Happiness is a trembling, exceptional state; seconds, minutes, days that you know simply can’t last. And sorrow at its absence doesn’t come afterwards, but at the same time. Because with happiness comes the terrible insight that nothing can be the same again, that you are already missing what you have, you’re worrying about the withdrawal pangs, grief at the loss, cursing the awareness of what you are capable of feeling. "
