CSection 1/24, freaking out!

I've had my csection scheduled for months, and this is my 2nd one (first was emergency so very different circumstances) but I'm starting to FREAK OUT and panic!! Tomorrow is my last day to clean, nest, get things ready and Tues 1/24 I go in at 515am for a 715am csection. I'm so excited to meet our little girl but so nervous for major abdominal surgery that I'll be laying there awake for! Also worrying about my 17 month old son and how recovery will be once we're home. Anyone else scheduled that has some good advice for presurgery nerves?
