I have been in the medical profession off and on for about 10 years. I am on the road back into the profession again, I guess I just can't resist after all...LOL. One of the things that I have learned along the way is to try to avoid the politics that go along with this job or any other for that matter. You will run into a lot of negative people along the way because they are definately overworked and severely underpaid.
I realize this is easier said than done, but keep your head up, just do your job to the best of your ability and leave it at the door when you go home. Try as many different areas of nursing as you can and sooner or later you will find a niche that suits your needs and people that will be there to support you when you need it.
I ran into some of the problems that you are describing and now that I look back on it, it wasn't the people that I worked with that created the problems, it was the admin. who had no clue what nursing or medicine was about. All admin thought about was the bottom line and how everyone could, including the nurses, do more with less. They even went as far as telling the nurses that "nursing" was no longer a profession and that things were going to be run like a business...obviously this has not worked out and all they accomplished was to drive out most of the quality nursing staff. From what I have seen and heard, nursing shortages are cyclic....from time to time there are shortages for various reasons and then peopl wise up and make the job much more attractive to people, then there is an influx and places can be overstaffed and then the fun begins all over again.
If you have any questions you can PM or email me...I am in Florida too and scuba just happens to be one of my many passions. Good luck to ya.
