I have been following your posts because I was experiencing similar physical symptoms during my clinicals at school. They have decreased over time at work, but I'd be lying if I said they are gone completely. I'm ready to leave bedside before I finish out a year.
I've tried for so many positions and I receive the same feedback more often than not. A nurse with more experience, or an internal candidate was selected. Sometimes it's the physician who doesn't want a nurse with less than one year.
If I don't get anything by my 6 month review then I'll be asking to drop to part time. My manager supposedly does not grant transfers. I made it clear during my interview this would not be a long term job. A year at most. I have one more month until I'm eligible for a transfer however I've been applying early in case HR is willingly to factor in I need to give a month notice.
I hope you land something soon, and return to post about it!
