If you are having doubts now, you may want to investigate career paths that are more appealing to you. If you get into a career field just because there is a shortage of people in that field, and NOT because you have a genuine interest in that type of work, you will feel trapped and unfulfilled in your work. If you are paying for your nursing education yourself, you will be reminded of what may not be a good decision for you, personally, on a monthly basis. You should definitely try to work in a field that you find interesting or exciting.
Nursing is HARD WORK. Some people feel called to the profession, love the work, and find great satisfaction in it. The down side is that there is not always a great deal of respect for the sacrifices you can end up making in helping others. Compensation and the number of hours you may be asked to work may be unsatisfactory - especially as a new nurse. The patient load can be difficult to manage and still provide high quality care. Despite universal precautions, there is the risk that you can become infected with different illnesses by the people under your care. In some employment settings, you are also more likely to be abused by your own patients (dementia and psych patients come to mind). Nurses also are reputed to "eat their young." As a new nurse, you may not get as much support as you would like. These are just a few considerations. You really should determine if nursing would be "just a job" or a labor of love for you. If the former, you would be better off seeking something that you would enjoy doing even if you didn't get paid for it. You would then be able to work at something that you looked forward to doing, and you would probably find yourself very well-compensated in the long run.
If you like working in and around the healthcare professions, you might look into some of the allied health professions (radiology, occupational or physical therapy, speech therapy, audiology).
Good luck to you in your decision and in all of your endeavors!
