Trust me, I totally get it. I feel like an idiot occasionally too. I've been a nurse for 6 years now, and there are always things that come up that you've never encountered before... but that's normal. Because you don't know everything, and the day that you think you do... It's time to hang up your scrubs. When I first started working the floor (after a year and a half at a desk job) I felt like I was going to be a complete failure. I didn't know how to a quarter of what the other nurses did, and I didn't know how to answer the questions my patients had. But that's ok too. Because it all comes with experience. If you stick with it and don't give up on yourswlf, it will start to get easier. Stop avoiding the other nurses, you won't ever learn that way.
