Point blank you are in a field unfortunately of primarily catty females. Keep your head up, do not let it bother you, be strong, do your job which is what your there for...the patients.... At the end of the day, if you know you did what you were supposed to do and you set your patients as your top priority, you will go home feeling accomplished. That catty female nursing crap will never go away unfortunately. Just remember what you got your degree for and call it a day.
