Its alright bro here is some advice since I've been through surgery before:
-ALWAYS listen to what the doctor tells you for the awake part
-Think what good this will do for you in the long run
-Try to stay chill, if you freak out to much it can lead to other serious problems.
-Try to take your mind off the surgery for awhile until you get their, just try to keep chill and relaxed.
-Think about how useful the surgery is gonna be, its going to help you big time.
And that tis WIC's steps to outlasting a surgery, Good luck buddie
