Grieving, and Thinking About Grieving

Are these jottings morbid? I once read the sentence 'I lay awake all night with toothache, thinking about toothache and about lying awake.' That's true to life. Part of every misery is, so to speak, the misery's shadow or reflection: the fact that you don't merely suffer but have to keep on thinking about the fact that you suffer. I not only live each endless day in grief, but live each day thinking about loving each day in grief.
