Right now I'm reading Start by Jon Acuff. (If the rest of the book is as good as the first half, I will share a review later.) Acuff had the same trouble and came up with a five-step secret in order to survive.
1. Admit that you can't possibly get it all done.
2. Give yourself the grace to accept that as a reality, not failure.
3. Do the things you can do with your full attention.
4. Celebrate what happens during Step 3 instead of obsessing over the things you didn't get to.
5. Repeat as necessary.

I think this list is going by my kitchen sink.
