Wanting to do this.. but not sure how? a bit of a crisis

Hello everyone!

Bit about me- I already have a Bachelor's in a science, but unrelated to nursing, field. I also have a full-time job/career. But I am very unhappy with it and certainly don't want to do this forever. Currently I am unmarried and have no children- which as it pertains to this, may be a good to bad thing. I have decided that I would like to go to school to pursue an ADN to become an RN, particularly in NICU, and maybe even become a Traveler one of these days (that last part is just a maybe- guess it depends on if I'm ever able to settle down at some point). My dilemma is nursing school- I have already talked with a counselor with the local community college and know what I have to do to apply to get in and such. I only need one pre-req course (A & P) before I can apply to get in. I can take it online this fall and continue to work. After finishing that, I can apply for NS, but would have to wait for the Fall 2010 class.

What I'm worried about is the finances- I have a pretty good job, but have alot of responsibilties that I alone have to take care of (mortage, etc). I'm pretty sure that I could save up for the cost of NS between now and next fall. And of course, there are scholorship and financial help available- a hospital nearby has a scholarship that you can apply for that is full-ride for NS, with a one-year employment commitment to the hospital once you are done with school. So there's that- but I'm thinking- what about living expenses? I can't imagine just stop working and going back to school. I'm in my late 20's, so I'm not being supported by my parents, nor do I have a husband to support me; how do people do this? When I asked the counselor if it was possible to continue working, even if just on a small, part-time basis while in school, she looked at me like I was crazy and said that it really wasn't a good idea, nor possible and that the program is really that intensive that you just don't have the time to work. So I don't know what to do. A friend of mine that I went to college with, also went back to school to become an RN, but she just moved back in with her parents and I guess was more or less supported by them while she went to school. My parents live out of state from me, so getting into a program near them would be kind of iffy, and our relationship over the years has been a bit strained, plus mom is going back to school for teaching, she's seperated from my step-dad, it's all a bit unstable at the moment; so long story short, I'm sure my mom would love to have me, but I'm not so sure that it's a good idea, nor really possible. I'm also worried about insurance! What about that!? If you aren't working, nor have a husband to carry you on his insurance, how do you have insurance while in school? ahhhhhhhh!

And I guess my last concern would be balancing my desire for pursuing this career and having a family someday. I'm not sure if I should do this now, and push back having a family later; or should I continue what I am doing with my current job, hopefully meet someone and settle down and have a family and then go to NS later? Which would be harder? NS later or kids later? I'm just so afraid that if I go after this now, that, say 5-6 years down the road, when I go to start trying for a family, that conceiving is less probable, and I've given up my chances of having a family for the desires to be a nurse. It's not like I can start a family ~this second~ anyway- but these are the things I worry about.

I would appreciate any advice. Thanks so much.
