Prayers going up that all goes well. You've done all you can (including prep!). Now it is in the doctor's hands. Let go of anxiety and let others do what they they're trained to do. Your only job right now is to rest. When you wake up, your job is to heal. All else will fall in between those two requirements. We'll all be here to support you and see you through this. Lots of prayers are being said for you right now.
