Straight up: *grabs Elle's shoulders and shakes her* snap out of it, sister! Stop this negativity!
That was harsh, I know
But people do this all the time (not the shaking, but going back to school- the shaking is more of a 1940s medical idea.) You're more than likely going to be active in the job market for another 25-30 years, so no, it's not too late. You'll find a job. Nursing school is hard, but it's all going to work out. Find the accredited schools in your area, do your research, check out their programs and make a decision.
There are a lot of ways to skin the nursing school cat. Maybe look into the job market in your area and think about places you think you'd like to work in the future to see if they require a BSN or would expect you to gain your bachelors after so much time. Do not be discouraged to find you may have to take a few prerequisite prerequisites i.e. more basic math courses if you have to take algebra. It may behoove you to look past ADN requirements and see what specific classes you would need to transfer or gain entry into a BSN program.
Finally, I'd recommend a community college or similar for cheaper tuition and then either apply for their ADN program or transfer to a bachelor program if needed.
