I really hate the way I look
Why do you hate the way you look?
I have a big nose.
It's wrong not to accept your looks.
But I'm ugly and so annoyed by my nose. That is why I want to get a nose job and look good.
Everyone has their insecurities, it's very normal. If this is disturbing your day-to-day life, then maybe it is a good idea to consult a plastic surgeon and mental health specialist to see if this is the right idea for you. You deserve to be happy about your looks.
