My friend Emilin lost her mom today. I know there is nothing I can say, here or anywhere else, that is going to make that any better. I don't know anything about loss that hasn't already been said elsewhere--I have no advice, no words of wisdom--just my whole heart going out to you and your family today, Em.
If you haven't already done so, go read Emilin's blog. It's one of the most beautiful, terrible, inspiring things I've ever read.
