I don't think I can work as a nurse, but I've already got a degree.

So I've ranted a bit about struggling to find a job. I have had a few interviews but they don't go anywhere. I skipped my interview with the ER today because I began getting anxious at the thought of working in the ER and all the type of patients and trauma I'd see and I worry I wouldn't be able to do my due diligence for those patients. I feel this way about any unit though. I don't think I'll be any good during codes, RRTs, etc. I'm an extremely timid man and I did fine in clinical but we didn't have any sudden changes in patients while I was there. I think the reality of being a nurse is setting in but I'm in too deep. Not sure what I can do at this point.
