Im trying to figure out the same course of action as you are right now. I've decided to do EMT basic because I want to do Trauma/ ER. I do think more jobs will be available for CNAs rather than EMT-Bs but they are out there for both. Ultimately you should do what you think will be most beneficial. I want to be a Flight nurse so I need the EMS skills of patient transport and rapid assessment which being an EMT will provide. I agree with the other responses on switching from psych to Nursing. Im now pursuing a second bachelors and wished I would have done nursing the first time around. Save yourself the time and money and go into the field you want to be in. You can always get a minor in psych.
