suddenly her whole mind revolves around it endlessly. --Yes there was some language that was exactly that. (Which I probably highlighted, along w/half the book).

I thought her wanting to just sleep, sleep, sleep was another aspect of it.

I also thought this was super well-observed:

And this absence of acute, unbearable pain seemed to her unjust, as if she had been denied some exquisite solace of suffering which the full acknowledgment should have given her ... Or was it that she lacked the capacity for the acme of suffering? “No, no!” she denied fiercely. “I’m human like everybody else. It’s just that I’m so tired, so worn out, I can’t feel any more.” But she did not really believe that.
