Anxious Traveler

I was wondering if any other traveler had my "problem". I've been a nurse for 4 years now and traveling for most of them after my year or so on staff on a med/surg floor. My assignments have all been pretty much med/surg and they've all been pretty ok, I've been treated well by the staff I worked with, and I made it out alive. Yet, I still get so anxious everytime I have to go in! I feel so intimidated by the nurses and staff that work there regularly, feeling like I shouldn't ask them for advice or direction since I'm not "new" to nursing, just to the facility. I wasnt to enjoy the months and take away everything I can from the assignments.... but this dang anxiety ruins it for me!!!
