I've recently been considering a profession in nursing. Question number one I was diagnosed with ptsd a few years ago and I do take some medications mainly an anti depressant, a medication for anxiety this is an as needed medication, and a sleep medication. My question is, is there any reason my diagnosis or medications would shut me out of the nursing field in general? Is it possible that I may just need to avoid emergency room type of positions? Question number two, to be perfectly honest I'm drawn to either psychiatric nursing, or possibly a LMHC, or LCSW I would say mainly because I'm interested in helping veterans and being involved in the therapy process so do psychiatric nps often get involved in this side of the house? And my third and last, I'm terrified of needles. I can never look when someone is sticking me and my hands often shake around needles. Is this something that can be overcome? Thanks in advance.
