The advice "you need a year of Med-Surg" is so outdated! I heard the same thing from almost every one of my nursing instructors. I spent six miserable years in Med-Surg because I listened to them (thinking I would only do one year) then I got 'stuck' there. It was soooo hard to break into a new nursing specialty without having any experience in it. During my new grad hospital orientation, I was sitting next to other new nurses who were going straight into the ICUs. I remember thinking, 'why didn't I do that?' It's one of my biggest regrets to this day.
I eventually wound up where I wanted to be in the first place; the Neonatal ICU. But I had to do a lot of legwork over the course of a couple of years. I put out tons of resumes, went on many interviews and really had to 'sell' myself as someone who could excel in a completely different specialty.
So, make a clean break now and go where your heart leads you...you won't be sorry! Nursing is really a wonderful profession. There are so many areas to explore. Med/Surg just isn't a good fit for you and that's okay. Good luck!!
