Rhinoplasty in One Week... Excitement Vs Doubt! - London, UK

My nose has always bothered me in my teens, when the bump started to develop, and worse still, I was teased by my family with comments like "she'll grow into it" and "look at her profile" - perhaps not meant hurtfully, but this certainly sharpened my focus on the offending nose. I have been thinking about getting a rhinoplasty for the past few years but was put off by cost, people knowing, risks etc. I work in surgery myself and didn't want any colleagues finding out. More recently, despite feeling quite happy with most of my other attributes and accepting myself, I've felt a desire to improve on the nose and banish my hang-ups for all. I don't expect it to be perfect, just less prominent, less bumpy, and not as downturned at the tip. Face on my symmetry is pretty good.

Having chosen what I believe to be a great surgeon, discussed my hopes and concerns in consultation, and planned admission for the op, I'm now having moments of fear, minor panic even that things will go wrong, or I'll hate my new nose, or it'll banish the "me" from me. I'm petrified that after forking out all that cash, I might be less happy with it than I am now - worst nightmare scenario. Another factor, though this wouldn't stop me, is the fact that even though I'm 30, my parents are very old fashioned and would be distraught if they found out. I have my dad's nose, which looks charming on him... but it's not particularly elegant on me! The guilt about removing my dad's nose from myself is so great that I'm considering telling them that something fell on my face and broke my nose :S (they live 10,000 miles away and I only see them once a year) So after all these anxieties, I almost talk myself out of the op on a daily basis (7.5 days to go)... only to then look at my pics, esp in profile, and want it done after all. Is that normal?
