I just wanted to chime in and say that I have had cosmetic surgery done and it is the best thing I could have done for myself. I have never regretted it one tiny bit and actually don't know how I'd feel if I didn't do it! I did not do anything that looked fake or unreal, no one would even know, except that I look fabulous hehehehe just kidding...but I was very happy with the end result.
All I can say is that if you have the means and support (someone to take care of you after surgery), go for it, once you know all the risks, procedures, personal results and so on.
I am not a proponent for changing yourself, but I see nothing wrong with self improvement. It makes a world of difference in the way you see yourself and your internal happiness.
Good luck hun
Take care.
