I hate my job.

I seriously hate my job. It makes me an absolutely miserable person. I cry constantly. It gives me the worst anxiety ever. I work in the medical field in a very well known hospital where everyone wants to work...and the floor I'm on is one of the hardest floors and it's physically and emotionally draining. We can't keep any staff, my co workers are so conniving and fake and flat out suck (only care about themselves) and management doesn't do diddly squat to help us out yet they think they do. The ONLY three things holding me back from leaving is the fact that this is one of the biggest hospitals in the area where everyone wants to work, the pay is too good for someone who doesn't have a college degree yet and the benefits are amazing. I don't know what to do anymore. Has anyone else ever been in this situation before? Cuz im seriously lost.
