As I was reading your post..I kept saying to myself this is totally me 3 years ago! My first job was on a IMCU/stepdown/tele unit. And I was feeling the same way you were--I wanted OUT of bedside... I was working night shifts feeling OK during the night but then the day shift nurses would walk in and give me such hell in the morning that I always felt like I was doing a terrible job/stupid. I left many mornings crying while driving home I was so upset all the time. I would also be so hard on myself when I made mistakes. I never slept because I couldn't stop beating myself up. I was miserable (or so I thought).
So, I left bedside altogether after 1 year.. I ran to a nursing office that was going to offer me to stay in the office for a few months and then would train me in endoscopy... Long story short, they never held to the promise -keeping me in the office for an entire year and (lost all of my clinical skills) and office nursing was not any better to me (and you get paid way less). It was less stressful yes, but I felt like I was no longer a "nurse" anymore. I had no more fun stories to tell my friends and my life felt boring.
Fast forward--I ended up leaving to go back to bedside at an LTACH (day shift!). I have been here for a year and I wish I never left bedside. I lucked out here because the nurses here are always helping out if I'm behind and there's a "help everyone" attitude as opposed to a "nurses eat their young" atmosphere as I had been in.. I wish I had stuck it out and maybe asked HR to try a new unit or stuck it out to get on day shift..I didn't realize how much bedside nursing taught me and how I wish I had found out that the grass was not greener on the other side. I often find myself saying..why did I ever leave? I wish I stuck it out longer because it actually wasn't that bad. Its crazy and hectic every day of where currently work-- But with time I have learned to appreciate everything I learned in that stepdown unit.
In conclusion, OP--I stress the grass is not only greener. I suggest if you have a good team stick it out for a little longer.
Remember it takes a new nurse a little longer to really feel comfortable. but also it may be helpful to change your thinking a bit. When crazy things are happening. accept it, and realize EVERYTHING is a learning experience. If your day feels crazier than other nurses- say thank you because you will be a way stronger nurse after all of it. And when another patient has the same thing happen you will be a pro and know what to do.
Another tip--take care of yourself OP! Be sure to eat well and get your rest!
Also, you may be like me where night shift is not for you.. (you have more chances of getting to day shift if you stay).
If you are absolutely miserable- then start interviewing elsewhere!! There's nothing wrong with interviews and you don't have to take a job if you get it. And do not feel bad for the manager--this is your life and your nursing experience and he/she will understand. Everyplace is different. And perhaps this isn't your "niche". Theres so many places for you to go, OP. and you are luckier than most having 9 months in a step down as a base! Don't give up!!
