I think the trick to surviving the darkest nights is not to pretend the dawn will never break, but to trust that even if it doesn't, you'll find a way to make your own light. There's a certain stubbornness required, isn't there? A refusal to surrender the possibility of warmth, even when every cell in your body screams that the ice age is permanent. It's not 'positive thinking'; it's more like a quiet, internal defiance.
