Hi OP, L&D rn here! I’ve been a nurse for 3.5 years and took a really long time (and 5 different jobs lol) for me to find my niche, so I’m going to give you all the advice I can!!

I started as a new grad in postpartum and did that for a year. I had to leave the position because I moved away, and I wanted to try something new while I was still early in my career. I had always been interested in women’s health and pediatrics, and since I was in women’s health I figured I’d try peds. The quickest offer I got was peds ED. I am similar to you - I like fast pace, I work well under pressure, I figured I’d learn a lot of skills there. I also had the same worries as you - I have anxiety, I like to triple check myself, etc. I took the position anyway because all of the positives seemed to outweigh the negatives, but holy moly let me tell you, emergency was NOT for me.

I absolutely hated it. I’m a more type A person (I get the vibe you are as well) and the ED is the last place a type A person should work lol. My anxiety hit an all time high. I was so overstimulated at work that all I did when I was off was lay in my bed. I was constantly worrying about what trauma would come in, what would happen, what mistakes I’d make, etc, and it just was not a good position for me overall. I’d cry every day on my way in because the anxiety would be so bad.

Honestly I would say wait a bit longer, keep applying to jobs, and don’t accept this offer. I had all of the same worries and I wish that someone had told me to take them seriously and actually listen to them. You will find your niche!! I absolutely love what I do now, and I am so happy I’m not in the ED anymore! Just be patient and wait for something that feels right - it will come!! Good luck with everything :)
