Finding it hard to concertrate on anything but my up coming surgery

I am having a really hard time trying to work and concerate on any thing but my surgery. I am excited and scared at the same time. It's not like I am not busy and don't have anything to do. Between work and home I am very busy but I am always thinking about wls. What if I am doing the wrong thing? What if something goes wrong? What if I can't lose any weight after the surgery? So many questions! I read the post every day and that just gives me more questions to try and figure the answers to. Any suggestions on what will pass the time away. My surgery is November 21, 2003 in Dalton, Ga. I have to be there at 6:00 am. I just wi**** was tomorrow.
