A few years back I was in and out of the hospital having surgery on an average of every two and a half weeks. It sucked. After the first surgery, which was emergent, I spoke with my doctor. I told him something like this:
"Dr. Smith, I'm really kind of stressed out with all of this, and lying on a stretch in a hallway/room waiting for it to happen increases my anxiety a lot. Can you suggest something that might help lessen this for me so my b/p isn't so high and I don't worry nearly so much?" See. . .I put it on HIM, using my words to say, "oh you're so wise, I need you, take care of me." LOL Men are kind of stupid that way. So he fixed it so that in pre op I'd get some Versed (you can ASK for this and no one thinks you're a dopie) and then left specific instructions that the IV, all forms, etc were to be completed right away, and I was to be left alone. No chatter, no banter, no "what are in you for" kind of talk. He also suggested I bring my iPod. I fell asleep with one bud in, and later when I woke up in recovery I discovered one of the nurses had been kind enough to put that bud back in my ear, and turn it back on for me.

My sister's a nurse and though some of them are royal pains in the ***, there are some really good ones out there too. Talk with your doc first, but I'd suggest also identifying ONE nurse when you get there who you feel might understand and just tell her, "I'm awfully nervous about all of this." That's all you need to say. The goods one will pick up on your anxiety and will try to help alleviate it, b/c the reality is a calm patient is a good patient, and anything they can do to help you find that calm place is going to be helpful to them as well as you.

Good luck hon!
