I think folks have some good comments. One I disagree with is to stop applying for open positions. It usually does not take long to apply once you are registered as an applicant with an employer. End/beginning of calendar years and also fiscal years are often the times employers have budget to hire new nurses.
Some employers are better than others. Unfortunately the better ones can be harder to break into. On the other hand, you now have some experience, and should have a better shot compared to when you were a new grad. Are some of the units on your hospital better staffed than others? Moving within might be another option.
