Nay,
I spoke to my parents about how they were feeling leading up to my surgery. My dad took it very hard, but bless his heart he tried to be strong for me, and I appreciated it.
Leading up to the surgery, the day before we didn't talk about it (my choice). The morning of, I simply told them I'd see them tomorrow, and they took me to pre-op. My surgery was 14 hours long, and I woke up in ICU. I had arranged for them to call someone for a surgery update about 9 hours in, as I didn't want them at the hospital (too stressful to sit and wait), then my surgeon was kind enough to call them when it was done (at 9 pm), and give them the update. Knowing they were getting info eased my mind.
They then came to see me in ICU the following morning, although I still have no idea at what time I woke up.
I gave them a list of stuff to bring to the hospital before hand for when I was moved to the ward.
You will be stressed, it's a given, but try and focus on after surgery rather than the surgery itself, as that is totally out of your control.
Good luck tomorrow.
