You can only exist as far as your mind will allow you to exist, and I think chronic pain will stop time dead in its tracks. You feel like you're the only one, and how unfair it is, and a million different feel-sorry-for-yourself type feelings.

If you think about evolution, sleep, at some time, was a dangerous undertaking. You lie down in your cave or shelter, and along comes a predator and has you for dinner. Many creatures do not sleep or sleep while standing so they can escape from dangerous situations.
