Breast reduction

Hello.

I am getting a breast reduction next Tuesday (finally.) I am 28, 5 feet and have DDD/E breast. I'm scared a bit because I have never had surgery before and not sure what to expect. What does it feel like to be put to sleep? Then you have to sign those document that it's a possibility you may die? Like that's some scary stuff!! I know it has to be there on the forms you sign but still! Anyone willing to explain to me and ease my mind a bit? Share some stories perhaps? 😉
