My first surgery

I know this is really off topic for this app and I apologize. But I'm super nervous and don't want to admit it to my family. I have to have my first ever surgery and I'm honestly very scared. I have a cyst in one of my sinus cavities and between my nose and too much tissue is one of my cheeks and have to have them removed. I've read up on it and obviously talked to the doctor. I'm not really scared of the surgery itself, moreless being put under.
