It's just that... you know. It's surgery. Sometimes, things happen. I've been dreading that aspect of it for weeks now, and even though some stress will be involved in the first two weeks of her being home and not able to do much for herself, most of it will pretty much evaporate as soon as I hear that she's out of it okay. I might hear as early as 8 or 9 am; I might not hear until later in the morning. Who knows.
ETA (Tuesday morning): She seems to have come through it all just fine and is Resting Comfortably, as they say in the hospital business.
