Ziggy, the psychological immune system explains a lot for me. While we think we're making "sense: of what has happened to us, we're actually revising so that we can feel better. It's a good thing because when there's a true catastrophe —someone close to you dies, or illness—making sense of it first and then seeing the possible positives stops you from heading for the nearest ledge. But it's not hard to see how there's a slippery slope here and how the cultural tropes with the relentless tattoo of seeing the bright side can also get you to a place which is neither healthy nor realistic.
