I am with you 200%. I am a new nurse, I have been on the floor for 2 months now. I feel so incompetent, I cry a lot, yesterday I infused the fats from the TPN in 1 hr instead of 12 hrs. I question the same things you are. I see my other coworkers, also new nurses already on their own and they offered me instead 2 more weeks of preceptorship, which is a good thing but makes me wonder if I am a good fit. Is difficult for me to shake it off. It wakes me up at night and I feel kind of depressed overall.
