Interview tomorrow and I want this job!

Alright.. so I have an interview in the am and I have never wanted a job more than THIS one. I am a pack of nerves and hope I can keep it together for my interview. I am usually very good at interviews and have gotten any job I set my mind to. However, the difference is the other interviews I was confident and had the notion that I don't NEED this job, there are plenty more and they would be lucky to have me. With this job, I NEED them and there isn't plenty more of this~ this is IT:bowingpur. I made a mistake telling my family so of course I have that added pressure.

Any ideas on how to relax during the interview? I already wrote down numerous questions they could ask- do you have any questions that you can think of that might throw someone for a spin(related to nursing)? Any last minute pointers?:uhoh21:
My biggest piece of advice is just to remember to breathe! Take that nice 10-second breath before you start (5sec in thru your nose, 5sec out thru your mouth) and then any time you start to feel the butterflies or they ask a question you are tempted to freak out about, take another one! The last time I had an interview like that (4 years ago) I was doing it after working the night shift, and it ended up being a 4 hour interview with several people! BTW, I got the job and hopefully so will you!
