I think it's natural to be nervous and a little scared. I just had surgery Monday. I never had a surgery before, so I wasn't sure what to expect. They were hooking me up in the or and the next thing, I'm waking up in recovery:) Not bad at all. From now till then, fill your mind with positive things. What you watch to even the music you listen to. Mentally prepare yourself. I'm not sure if you're a religious person, but scripture is one of the best things to fill your mind with. You will do great!
