How can I go through a surgery in hospital?

How can I go through a surgery in hospital? although I am only 22, I just thought that this can be an issue when I get old. I have very severe stutter, 0 friend (maybe just have some simple talk or had 1 or 2 dinners with few people). I can handle the loneliness because I like writing novels, but it's miserable that no one takes care of me in the hospital and no one picks me up after surgery. How do you handle this, do you all have friends? I think I have autism now, nearly dumb.
