I tend to laugh when it shows up in my personal readings, because it inevitably carries a message of "Silly woman, stop overreacting! Quit being a drama queen; this situation sucks, but it's survivable. What a relief, it's almost over! And it's WAY better than you think...just drop the anxiety and look at the dawn."
Does it accompany endings? Yes, sometimes. But it's a card of reacting to extremes, well beyond what I should, of allowing my thoughts to control me instead of the other way around. Seeing it tells me immediately that I've gone way off track and need to pull myself together. Even when it foretells an ending, it's never as bad as I'm making it out to be.
As another poster said, give me this over the 9/Swords any day.
