It is for this very reason that I am looking at making a career change myself.
I absolutely love the doctor I work with and the patients are wonderful, but my 2 coworkers are just so unhappy and miserable in their own lives that they bring me down to depressive levels. I've tried to just ignore them and do my job and be done with it, but I just can't any longer.
The final straw was when Rich was sick. Not once did either of them reach out to me. When I returned I was greeted with attitude and ignored. Never one did they ask how Rich was. I realize life is too short to be somewhere where you are unhappy.
