I was always self-conscious about my nose - it was a "family" nose, with a slight hump in the bridge. I felt as if people were horrified by my profile (even though logically I know that's not the case). I always hid behind my long hair, and had no self-confidence. I made the decision to talk to a surgeon about rhinoplasty at age 23.
My doctor didn't try to create a nose that didn't work with my face. He explained that a lot of what people dislike about their profiles is not so much their noses but their chins - it's all about contrast. I did have a chin implant, and he used cartilege to build up the area at the top of my nose; that area receded and made my nose look larger. He smoothed the bridge out and refined the tip slightly.
The day after the surgery, I thought for certain I'd made a mistake. I looked like a pig-monster, my entire face swollen and my nose taped up such that all I could see were my nostrils. My eyes were black and I felt terrible - you swallow a lot of blood during rhinoplasty. However, day by day, it improved. The bulkier bandages came off and I could begin to see what my profile would look like; I was so excited. I had the surgery on a Wednesday; I was back at work two Mondays later - slightly swollen but feeling good.
Actually, I did look perfectly fine just as I was, but I'm still happy I had the rhinoplasty. 17 years later, I still love my nose and my profile. I don't know if I would be the confident person I am now if I hadn't had the procedure. If that's what it takes to make you free to concentrate on more important things, my advice is to go for it.
