Scared of surgery

So I'm getting a rhinoplasty in about 6 months in Beverly hills And I'm super scared of going under anesthesia and the possibility of not waking up. I have 2 kids and I need to be good for them. I already have anxiety and this is just adding to it. Has anyone gotten a procedure like this? What was your experience. I'm going with a reputable and pricey doctor and before anyone says u don't need rhinoplasty I was bullied since 2nd grade for my nose and I developed depression low self esteem and trauma. I remember hiding in the bathroom stall in recess because I wanted to be left alone. Anyways if you've had a surgery like this " cosmetic " please share your experience
