Not about the surgery, pain, or eating. Want to know what I'm anxious about? Being in the hospital room with someone and not being able to fall asleep!

I am so crazy when it comes to sleep. It has to be dark, quiet, and I have to have a fan on. Now, I know some will say that I'll be so tired it won't matter, but it does to me. Trust me, I had my tonsils out when I was 16 and was SOOOOOOO tired, but the girl in my room had the TV on and I couldn't fall asleep.
Does anyone know the steps to go through to get my own hospital room?
