Sending lots of positive thoughts your way. I hope your son's lip heals cleanly and quickly, poor kid. Having a swollen, painful lip is no fun. I know YOU think you looked like a mess but you and your family are looking fine (if frazzled by the situation). I hope you do get power back before Thanksgiving, esp with those temperatures happening.
The worst natural disaster I ever experienced was the Blizzard of '78; we were without power for about a week back then. That's nothing compared to what you're experiencing. Stay warm as you can.
