You sound like me a year ago! I also have a previous bachelors, started my nursing pre-reqs at TCC last fall, and work full time!
I found time-wise working full time and going to school full time not to be an issue. Now, I don't have much of a life outside those two things, but I still get enough sleep and have some time to spend with my husband. My friends, on the other hand, hardly ever see me anymore.
Luckily, TCC has lots of evening, weekend, and online sections of the nursing pre-reqs so they work with nearly any schedule!
Money-wise has been more of a challenge. Since my husband and I both have student loan payments on our first degrees, and I know I'll be taking out loans for my BSN (I'm going to OU-Tulsa, so I know I'll need loans then), we wanted to pay as we go through my pre-reqs. TCC has been fairly affordable for us, although it has been tight. They let you set up a payment plan to make 3 payments a semester, which helps a lot. It's really been a burden on us, but we've managed to not need any loans. I didn't spend too much time seeking out scholarships or aid, since I thought we'd be able to afford it and I want to be eligible for as much as I can when I transfer to OU. I'm sure there would be something out there, though! My paycheck goes almost entirely to TCC. We manage to live on my husband's minimum wage full time job paycheck....so it's not lavish by any means, but we're making it.
All I can say is - it's totally worth it. I spent a year waffling about whether or not to go back to school, and I feel like it was a year wasted. Just getting started and knocking out those pre-reqs feels so good!
I took almost all of my pre-reqs at TCC Metro - if you're planning to go to Metro campus I can give you some advice on which profs to take and which to avoid, if you'd like.
Working and going to school is hard, but it won't be forever.
