Hi Mrs West,
Being scared is a normal part of the pre-surgery waiting period. We all go through that, even those who didn't admit it to themselves. For me, whenever fear, doubt or cravings kicked in, I just looked at a photo of my 5 year old grandson and remembered why I started this journey in the first place. I want to be around to see him grow up, I want to be able to get on the floor and wrestle with him and play football. Find your motivation and keep something with you that reminds you of that. Use it to help overcome the fear.
As for pain, that is different for each individual. For me, there was pain after surgery, but I was doped up so it passed quickly. After that, while I was in the hospital, I had the pump that I could dose myself if I needed it. I only used it just before getting up the first day and a half after surgery. Once they released me, I had a prescription for pain meds, that is still sitting on the shelf, unused. Others here will report different results. I can say that all of us focused on what the goal was and everyone got past the pain.
You'll do great, but keep asking questions on here and if you need it, just ask for virtual hugs, we have plenty of those. (((hug)))
