2 weeks away and now a little scared?

Well Im new here. I have my surgery on April 29th, Im really excited. I have wanted to do this for at least 10 years, and now Im financially able too!! Woo Hoo. Im kind of scared now. Im afraid of everything, the pain, what if they dont look right, what if they dont feel right, what if the doctor screws up and oh I dont know... Can anyone reassure me of these scares? Let me just say Im not doing this because I want bigger breasts, Im doing it because there is a huge difference in size between my right and left side. Im hoping after all is done that they look as natural as they can. Can any of you tell me that what you have had done looks natural?
