Undertaker, I have been a nurse for 32 1/2 years. I have worked in hospitals, nursing homes, private duty and have been at this psych facility for 22 years, (as a nurse!) I graduated from a diploma school of nursing and went back to get my BS. Being a nurse is my defining character. I don't remember wanting to be anything else. (Except when I was 4 and wanted to be a ballerina and my gramma talked me out of it). Some of my jobs I loved and some I didn't. I never approached it as a 'good' job. In the Dark Ages when I started, I got paid $3.50/hour. I think that the desire to be a nurse must relate to who you are, what you are about. Your experience as an undertaker will be helpful. If you want to be a nurse you can. It is hard work, not glamorous, stressful, demanding, challenging, dirty, dangerous. But it is also uplifting, lifesaving, soul satisfying, spiritual, life changing, and eminately portable. In my years, I have always encouraged students, shown them everything I can, helped them in every way I could. Lord knows I needed all the new nurses I could get to come help me. I have also actively pursued the students who didn't care, who just wanted a job, who cheated on the work they handed in, and made sure they didn't come help me when and if they graduated. Nursing is one of those professions that defy a simple explanation. It is too many things to fit into one defination. We have not worn nursing caps for years because we don't have room for all of the hats we must wear on any one day.
Give it a try. You will have ample opportunities to change your mind during your education. It's not engraved in stone once you get started. If you want a taste, get a job as a nurse aid, QMA, CNA, however they are designated. Investing a little time in that area will let you know if it is what you want. In the meantime, keep your day job.
