sweetie, we are trying to offer you some support, along with some great advice.
Honestly, I think it would be in your best interest to start off in another program, and then transfer to nursing at another time. Now, you said the Dean suggested Gerontology, right? Well, IMO, that would be a fantastic start and it would absolutely increase your chances of being accepted. Anything that you can do will only help you.
I understand that you are upset, I know that I will be devastated as well if I do not get in...however, I will have other options to fall back on. (early childhood education, or practical nursing....).
Now, I'm not sure I understand why you cannot get a job off campus. A job is a job, no?
How old are your kids? If they are old enough, send them out to get jobs as well! You are a family, and if need be, you all need to contribute for a little while.
I really think you need to open up to some of the ideas that are being passed on to you. We are only trying to help.
