Any OR nurses out there?

I am a brand spankin' new, just passed my boards nurse and I was hired into the OR. I have spent the past few days in orientation and then I spend the next 5 weeks in the perioperative program. After that, I work with a preceptorship until I am placed on my own. The word TERRIFIED is a staggering understatement. Are there any surgical nurses out there who have any advice? I have a lot of pressure on me to do well, as I was told by about 10 different people that my department doesn't hire new grads so I must have really impressed them in order to be hired. I'm really freaking out that I'm going to screw up and they will realize they made a mistake in hiring me!! Any words of wisdom?? Thanks!!
