im a guy (18)

6 months ago, i was extremely insecure because of a mole/mark on my lip.. it was my dream to remove it for many years

i paid 400$ and got it removed and i felt very confident even now.. its amazing

however, before i paid the 400$ at the surgeon, i had already paid 60$ for a HOSPITAL surgeon but that didnt come.. so thats why i paid the 400$ to remove it INSTANTLY

..**now** the hospital surgeon has finally scheduled my meeting

1. now i started to worry about another mark which is on my neck, and back..
im losing sleep over this problem because:

Should i just let the meeting expire or should i go? i dont think the mark on my neck shows a lot since its my neck and shouldnt matter. and almost nobody sees my back.

so.. should i let the meeting expire as i have already removed the one on my lip or go there and go through the pain and uncomfortably again for my neck and back?

please help i have too much anxiety
