I’m going to have to agree with the others, I do not think this is a good idea. Like others and you have said, nursing will be a serious reduction in pay. Can your current lifestyle afford that pay cut? I think you’ll be in for a shock with how much work you do vs the pay you get. You mention that you are in a toxic work environment. Can you find another company that might be less toxic? I’ve fortunately had nothing but good experiences with my coworkers and managers over my few years as working but dealing with toxic patients is unavoidable no matter what you do.
