I am very nervous and have second thoughts all day long. I too am having surgery April 21st! I have thought the same thing... this is an elective surgery and I'm so scared! I've never had a major surgery, just had my tonsils taken out 3 years ago, but that's it. I just keep trying to stay positive because this is what I want but for the past 2 weeks its all I can think about and it has caused a lot of stress for me! So, I know where your coming from.
