I guess maybe this is obvious for must of you people. Just want to suggest that it is very important to be at least stable in some areas before surgery. Have a place to stay for a while if you don't have your own, if you are studying do what you need to do before the surgery for example ask for time off, or do it in summer if it is an option. If you broke up with someone you love, try to heal that before surgery. Be sure that you are doing surgery for all the important medical reasons not to proof that you are really in pain. Well and all the other suggestions that are post here. Don't let fear stop all your dreams. Sometimes fear paralyzed us before the body does.
I understand everybody is different.
