Take a deep breath and listen to some soothing music, Bandari or something. You can eat sweets the day before to make yourself feel happier (if you don't have diabetes). Find one or more people you trust to accompany you before the operation. If you are still nervous, you think, "Forget it, make him nervous. I won't know anything after anesthesia for a while." If it is not general anesthesia, you can communicate with the anesthesiologist and ask him to give you enough sedatives to ensure that you sleep soundly throughout the operation. I believe it will never be a pleasant experience to wake up in the middle of the operation and hear someone jingling scissors on you.
