Good for you! Your ambition, enthusiasm and previous experience will help you reach your goal of becoming an RN.
Have you considered a community college ADN program? This is often a less expensive means to the same end (RN). And if you have children in college as well, that may qualify you for Financial Aid grants and subsidized loans to help ease the cost of both yours and your children's expenses.
My CC nursing education cost about the same as a new car would have(a compact w/ manual transmission, locks and windows
) I covered it with a few loans and grants. Had enough for tuition, books & supplies, as well as incidentals like transportation, child care and lunch money. Not bad investment for a whole new career with excellent dividends.
