Called tonight-surgery in 7 days

I just got called that my surgery will be one week from today. I am scared, but I don't want my kids to know it. They are worried as it is. Clear liquids start immediately. No last supper of beer and pizza for me. Oh Well. I hope this is the right decision. I just don't want to die or be debilitated. My kids need a fully functioning mom. Pray for their peace and mine.
