I am i good enough for college?

sounds good to me - you seem to be concerned about other people in general, and that's what really counts. If you ever have trouble with nursing cles (some of them can be hard, such as organic chem) just take less cles, but stick with it. Don't worry about the money, once you become a nurse you will be able to pay school off. Maybe start with a community college first, if you're not sure? Good luck.
