I'm very sorry for your loss, Clarky. I'd say Kite, One Tree Hill, or maybe 40, but really, sometimes when you're listening to U2, a song apparently with a totally different theme will suddenly seem to speak to you in ways you'd never have expected, so it could be anything.
EC, for me at least Tomorrow seems almost too intense and raw to help you through loss. If I had to put it in words, it's more like keening than catharsis, if that makes any sense.
