Hi everyone, I have been working in a hospital for a little more than a year. I first started off at a psychiatric unit because I really did love my psych clinicals during school. However, I began having nightmares about my unit 8-9 months into the job (d/t some traumatic events that occurred). So after a year, I transferred to a ortho-surgical unit (that is still part of the same hospital/corporation) and am now working night shifts. I'm almost done with my 3-month orientation but I feel miserable and I'm constantly stressed about making mistakes. Within 2 weeks of my orientation, a patient passed away and I can't help but blame myself because that pt was under my care. My preceptor and manager told me I did the best I could, but I can't let go for some reasons. My unit's patient ratio is usually 6:1, so everyone is scrambling and charge nurse can never be found. I even found out that at least 11 people have quit within this year. I am at a loss, I don't know what to do. Is three months too soon to leave? If I leave, I don't know what other jobs I can do with just a BSN.
