@Molros - Firstly, stop stressing yourself about it. Too many people are just too opinionated and definitely have their blinkers on when it comes to "what they did".
This isn't a case of not wanting to.. this is a case of matter about the breast surgery, you had very realistic chances that you would not be able to anyway.
I would respond to these know it alls, granny included.. "well if I could, I would, but I physically and literally can't due to medical reasons. The choice is quite simply out of my hands".
If anyone asks me, my response is always, "If I am able to, yes". To me, it's the same as giving birth, I'd like to have a drug free birth BUT I have NO IDEA what my labor is going to be like so how can I say if i will or won't have drugs??
