Keep me in your prayers!

I went for my first job interview in over a year with a small fire and ambulance service about 45 minuates away. It went very well for the most part, i decided to ride with them tommarrow just a 12 hour shift. Which hopefully will be busey. They average 200-250 calls a year and the majority of them are trauma and cardiac (ughh!!!). Since they are just a BLS unit compared to riding with a ALS unit every week, i will the medic in charge in the back doing everything. Which really really freaks me out! What happens if i freeze on my first cardiac arrest and i am in the back by myself!! Everybody tells me that i will do great and it will all come to me when i am in that moment. I always wanted to be the one in charge doing it all but when you come to that point it gets really scary cause if you do one thing wrong you could kill that person or hurt them at the least and then there goes your license. But i have to put more confidence in myself. Its just like when i started working in a doc office and the first time i was the nurse by myself no one there to guide me doing it all, it was scary but it just came to me like i was a natural lol. So hopefully i will know something next week, i am excited and ready to go be on the ambulance paid.
