You say 'it really changed my life (sadly)'. Why sad about it?
Ever since I was about 13 years old, I've realized I don't like the way my nose looks; there's this little bump on it. Every time I see myself in the mirror, my eyes are drawn immediately to my nose. I've made up my mind long ago: soon as I get the money I'm getting that nose 'fixed'. Sure, I don't like how our society is so focused on looking good and all, but here's how I think about it: I only live once, and I want to make the best of it. So yeah, that also means I want to look my best. And my nose the way I currently have it, is not part of how I'd like to look.
I do think it's very sad the way some people's lifes are absorbed by a desire to look ~perfect~, whatever that may be. Some movie/popstars come to mind.
Have to say though, I like the way your nose looks before the surgery. It's cute. Still nice afterwards, but I don't think you should have been insecure about it (you should see my nose~)
