My big date is in two day...
Renea,
This is perfectly normal. I cried almost every day the week before my surgery and I could never figure out why. I think it is just a combination of emotions. This will carry on when you are post-op too. I have cried a few times for little things since surgery. It's like I'm just so emotional since I had surgery Thursday. Many post-Op's have told me this is normal and it will pass in time.
Hang in there and if you need support, you know where to go
Good Luck with your surgery!
Kelly
