What can I do months before the surgery to be prepared?

Hello I just got my surgery date(May 5th 2026) and it finally feels real. I want to be physically and mentally prepared for what’s about to happen knowing that it’s a very invasive procedure. I’m also really nervous about the aesthetic aspect even if my face changes for the better do you guys ever miss how you used to look or is it so subtle that you’ll look the same for the part?
