Take the littlest thing that needs to be done and start there. That's usually the catalyst for getting me going when it seems like there's too much of everything to get anything done.
I'm feeling a little bit the same way today. My daughter wants to get the dog tonight instead of tomorrow, so I'm trying to do today's work, and catch up the half a day that I got behind, and get the house ready for the dog, AND work with the dog. ay yi yi!
We'll make it. We don't have a choice.
