Highly suggest you get psych experience. Real experience. Flesh eaters, testicle removers, feces eaters, patients who cut their wrists and throat etc until they pass out or die. It just may not be for you. I have seen so many psych NP students precept at my work only to quit their programs after being exposed to real psych. There eyes were so bugged out having no idea what they signed up for.
There is a very good reason psych nursing is the least popular field of nursing.
