Katherine,

Best wishes for a successful surgery. I certainly understand your anxiety about the surgery, but many of us on the forum have been through it already. It isn't fun especially the first few days but you will do fine. Being in pain doesn't help with recovery, so take pain meds as needed.

I hope you can work something out with your professor about your class. There should be something they can do to accommodate your situation.

Post when you can to provide an update.
