Hi, chessylady!
I've never even heard of this procedure, had to look it up to see what was involved.
Your comment is the best: "Trying to think positively and look at the big picture." I know you've researched it and chosen a good doctor, and you're going into this with a great attitude. That's a big part of winning, so you're well on your way to success!
I'll send a prayer and lots of good vibes your way. I hope you'll let us know how you're doing.
Few things reveal your intellect and your generosity of spirit—the parallel powers of your heart and mind—better than how you give feedback.~Maria Popova
