I am a new grad that is just hitting the 6 month mark. I realized recently that I was driving in to work without the usual ball of nerves in my stomach. I am eating a decent lunch, and even snacks during my work day now. I no longer have diarrhea every day that it work. It definitely gets better!
I had (and still have) a lot of questions, and since I work in an ER there's not always someone available to answer questions. I have a little address-type book I carry with me that has things alphabetized..."C" has an entry for Conscious Sedation, "P" has an entry for Port-a-Caths, etc. Writing things down has helped me remember them too.
As new nurses, we are really hard on ourselves. For me it was difficult to transition from "top of the class" student, graduating, passing NCLEX, and feeling like I was on top of the world, to New Nurse, starting from scratch, trying to integrate everything I learned without missing something or killing someone. Hopefully with more experience, you will start to feel confidence and feel kinder towards yourself as you go through this major learning curve. Best of luck.
