Oh, Kcv19, I'm almost literally in your same situation! I'm about a month off of orientation (I did it on days as well) and working on nights. Our hospital is very small and so our night shift is super close knit so there are definitely times where I felt like I didn't fit it or I was being overly annoying but asking so many questions. But trust me, ALWAYS ask questions, even if you've asked them before. I kept on telling myself that I would rather be considered annoying than risking the health of my baby.
As hard as it was, I found a coworker who's personality and temperment sort of mirrored mine and stuck with her. Now sometimes I'll start off with, "I know this is a stupid question but..." and they don't seem to mind much anymore =] Some of the more seasoned nurses talk crap about the new grads and orientees right in front of us! But I've learned to ignore them, not gossip, and ask as many questions as I need to.
If you want to, we can message and complain about our experiences ;] and bounce ideas/questions off each other? It would be nice to have someone going through what I am!
