Congratulations on finishing your nursing degree. I'm so sorry that you've spent so much time and money on a career choice, only to find that you don't think you'll like it.
Nursing can be a very rewarding field. I've been in the Operating Room for 25 years, first as a Surgical Technologist, and now as a nurse. Nursing in the O.R. is much more technical than floor nursing. Your patient ratio is 1:1 (unless, of course, you're doing a C-section...there's the baby or babies.) Operating room nursing has been an extremely rewarding career for me. I honestly never would have finished nursing school, if I hadn't known that I was going right back to the O.R.!!! I've never been a talky, people oriented person, so I always had difficulty striking up conversations with patients on the floor. I also always felt like I was being pulled 10 different directions, and it was hard to multi-task the way a floor nurse has to. In the O.R. I can focus on one patient, one surgery, for however long it takes. Don't get me wrong, we can be 'crazy busy' in the O.R. (and usually are) but it's a whole different type of nursing. Before you decide to give up on nursing as a career, talk to one of your instructors and see if there is a way you can observe in one of the O.R.s in your area. There's many sub-specialties in O.R. nursing that can be fascinating....Orthopedic surgery, OB/Gyn, General Surgery, Neurosurgery, Open Heart surgery, ENT & Eye surgery, Urology, Pediatric and Plastic surery, if one doesn't tickle your fancy, certainly another would!
Good luck! I hope you are able to find something that you enjoy. Liking what you do for a living is 90% of the battle!!!
