I'm stealing this from my cousin.
"If you're having a bad day, handle every situation like a dog. If you can't eat it or chew it, pee on it and walk away."
And as for an update, the week has gotten MUCH better. Much, much better. I'm looking forward to this weekend (perhaps seeing Bond tonight?) and definitely looking forward to next Friday ("I'm so excited I wish I could pee my pants!"), so things are looking up.
