Should I tell my friends that I’m getting rhinoplasty? (Coming out)

Tomorrow at 10 o'clock... ! It's surgery!! (I'm nervous) This is my friend, whom I've been in contact with almost every day since high school. When I was young, I joked that I was going to get a rhinoplasty! We made fun of each other and called each other king-coats, and my friend even knew that I had gone out of my way!
 
But when I try to say that I'm having surgery, I feel like I'm going to tell other kids... Now, no one knows except my parents (except celebrities! Haha),
 and I thought they were really close friends, but this friend showed me a photo of another friend who had plastic surgery and said that it looked too big.. and said something like this... There's no guarantee that I won't send my nose to other kids...
 That's not to say I'm not someone who won't see him.
 I didn't tell him because I thought I'd see him within 2 months after the surgery, but when I saw him after the surgery, he contacted me every day asking if I did it secretly. You wouldn't say you were upset that I didn't tell you, right?
 
It's really a pointless worry before surgery; Still, it occurred to me and I wrote about it...
 I hope the surgery goes well!
 
Have you ever told your friends about the surgery date?
