I am miserable at work please help

Someone please help. I graduated a year ago. I started my first job on a trauma unit in July and worked there until February. The patients were miserable, the workload was insanely stressful, and my coworkers were malicious. The manager was fairly decent however. I started working on a mother baby unit in February and while the patients are better in general, my managers hate me and they are trying to push me out. Nothing I do is appreciated and I am scolded for any tiny mistake. I am miserable and it's safe to say I hate being a nurse. I went into this for the love of other people and caring for people and it's nothing like that. Night shift is also not for me but it seems that's all I can ever get. I want to apply for a school nursing job because it's totally different, the hours are better, no holidays and weekends, and most of all no malicious coworkers and patients. I don't want to look like a job hopper. Should I do it? Or start a new career doing something else?
