K.E.
Here's the good news. You HAVE a job. Look around, many people have been out of work for a year or more. Count your blessings. You say you like your job but you are not "fulfilled".
What does that mean? Few jobs fulfill us spiritually. In fact few jobs fulfill us at all. We are fulfilled by family and faith.
So, if you like your job is there a way to advance in your present career? Are you in management? If not would you like to be? If you had more interesting opportunities in your present situation would you be happier? Many companies will pay for education in order to keep good people. If you want to consider moving up, or into a different area, see if they have something in place to help you. You have experience in the hotel industry. Any industry can be rewarding and fulfilling, IF you are in the right job within that industry. Maybe you can check around the business and see if there is an opportunity in another hotel that would pay better or where the ability to advance is more readily available.
I'd stay put until your child is older. Your child needs you.
Nursing is a wonderful career. Remember that nursing it is a lot of work and although it can be extremely fulfilling, it, like any career is filled with the same politics, the same frustrations, the same difficulties that any career is filled with. Talk to people in the field, in any field you are interested in, do your research before you make any moves.
