I can relate!  What really jumps out at me is this, though.
Through all my specialty changes, and even a hiatus from nursing altogether, I've had to accept the above quality about my personality and slog through the awkwardness until I get to that new comfort zone--regardless of my age.  If everything other than the adjustment phase was a good fit for me, I never failed to at least begin to feel competent, knowing that there's always more to learn in any job.
It usually took longer than days (more like weeks) to feel more confident, but it always happened.
I find it really helps if you can find a co-worker who you can ask questions and who won't give you attitude or make you feel stupid.  That's invaluable if you're fortunate enough to have such a person in your midst.
All the best to you in your new job.
