First cesarean, third baby.

So this is my first cesarean. My placenta is like right on the cusp of my cervix, so they've advised this route. My first two pregnancies, I delivered vaginally. I go in next Friday for my scheduled cesarean and while I'm really excited to meet our little boy I'm low key freaking out. I've never had ANY type of surgery. I just need words of encouragement, I swear my mind always goes negative. Any words of encouragement would be greatly appreciated.
