I was so nervous for my first ba. I had my second one yesterday and because I knew what to expect I was fine. I think once you’ve been through it you’ll laugh at yourself for worrying so much.
Friends used to ask me how I could want something so badly yet be so scared.
As for what people say; my surgeon told me to ignore what other people think or say. Some will agree and be happy others won’t. I have never personally had anyone criticise the fact I had a boob job. I made it very clear I was doing it for me and no one else 🙂
