Wow it sounds like you've had quite a ride. In my opinion, I say go for it. I don't have the background like you do (no children, no degree yet) but it sounds like, for right now, that nursing school would be the best option.
And by the sounds of you getting too stressed out about a bachelors program, then def go for the ADN. You can always bridge over at a later date if you want.
And while you are in the program you can still be looking for a job as a chaplain if you would have the time to do that with the kiddo.
I say go for it. It wouldn't take long and you would have more job options. Can only go up from there!
