I wrote a reply but I lost it. Here goes again. I got exhausted just READING everything you've been doing with your kids and everyone else's kids! You do need a break, I agree. I'm glad you stood up for yourself and canceled the sleepover. It will great to get the snow, but then the kids may be stuck in the house again instead of going to school on Monday.
I know many people with big families. Hang in, there. When the oldest gets a drivers license then he/she can chauffeur the others around! Of course then you worry about them driving!
I'm glad your H is helping clean up.
