It's to bad you feel this way I work in the E.R.and am constantly exposed to hiv, hepatitis,and a host of other diseases you can protect yourself. Why did you really go into nursing ws it for the money? If it was for that then you missed the whole point of what a nurse is. It was never meant to be anything more than the giving care to those in needof your services if you allow yourself to feel all these negative feeling it's time for a vacation from nursing and try something else for a while or have you considered trying a new area that may have sparked some interest. It might be something to think about?
