Waiting for call back after interview worse than waiting for NCLEX!

Soooo I got a call for an interview for a BMTU RN and well, I fell in love. The position sounded life fulfilling, I'd be able to help patients who I believe I'd make an impact on, opportunities for advancement, continuing education... In other words, I'd retire from there.

Its been 2 weeks from my interview, and of course I'm freaking out. I thought I did well, we laughed, she nodded plenty, said "yes, that's good" a couple times. All the signs I've been reading on all the boards I've been googling to help with my increasing anxiety.

But No call she had told me on Tuesday she'd let me know about the decision early next week....that was last week. *sigh* what do I expect? Help me calm this overacting mind please
Have you written a thank you note to the hiring manager? Have you called to follow up?
