I am so sorry that this happened to you. I too have been in a situation where what I said or what I did was twisted around to make me look bad, or to attack my nursing skills. There was also an supervisor and her favorite sabatoging nurse duo show. Unfortunately, if you don't stand up to it now, it may not end. I
don't think you are necessarily in the wrong career, but probably the wrong job. Please educate yourself on horizontal violence at the following link http://www.nurseadvocate.org/hv.html
I know of another great site and I will try to find it for you. In the meantime, take care of yourself. You probably feel traumatized at this point- I remember how angry and shaken I was. There are lots of nursing jobs
out there. It took me awhile; I am an older nurse and seem to be a target for these type of people. I am a slow learner, but once I learn it I am very competent. Just type in horizontal violence in a search engine and you will come up with some amazing information. Keep tuned to allnurses.com-as you know, it is a wonderful support system.
Good Luck and keep us updated:
