Always feeling a bit anxious/stressful before each shift...need some tips/wanting to vent

[barcode120x]

So, I'll be walking into my 4th shift on my own tonight on telemetry after a 3 month long orientation/preceptoring program. Before each shift, I try not to think about what the night will be like, but I can't help but think about what could possibly go wrong. I have no problem providing safe patient care and doing nursing care/tasks and even charting. My problem is that I start to get anxious and stressed out when there is a change in patient condition and/or I have to call the doctor early in the AM due to critical, or almost critical labs.

What are some ways to like...not feel this way? And, how long will this thinking pattern stick with me? I know everyone always says that a new grad won't feel comfortable for at least a year, but are there some ways to cope with these thoughts and feelings? It's very uncomfortable to me and I'm pretty sure my BP is always elevated every night shift. I think one of the biggest contributing factors is the fact that it's late at night and no one likes having to call a doctor in the middle of the night. I've had my share of not-so-friendly doctors when I was orientation on day shift and I'm quite scared to contact them in the middle of the night for an appropriate reason. So far when I had to, I've had very good doctors.

I will say, it is normal to have some form of anxiety before a shift-I've been a nurse for 10 years and have developed a form of "hyper awareness"; it prepares me to the school of thought that ANYTHING can happen. My solution is deep breathing and meditation before going to work, which helps.
