Now cut it out with all those horrible demeaning thoughts, BPNurse! The fact that your interview went so well that they offered you the job is pretty awesome just in and of itself! You're not broken and unfixable. This particular job might or might not fit the bill, but that'd be a hell of an extrapolation from one of those thoughts to the other!

I can't, of course, tell you what you should do. The only (remotely) close experience I have is from a couple of jobs ago. Calls at any hour (sometimes with immediate departure), work any shift ('round the clock work), but expected travel radius of "only" about 2 1/2 hours drive. I kept more stable than I would have anticipated. Which is not to say totally stable, just relative to what it "should have" done to me. For what it's worth.

Psst, Don't read this next bit, BPNurse, it's something you need no reminder of…just letting people know a bit about our fine state...

(I do feel compelled to point out to those that may not realize that "all over the state" is substantial. This state is 98,380 sq mi. In comparison (only because I know your location off the top of my head, Venus -- to be able to compare...), Czech Republic: 30,450 square miles. Sooo, we're talking more that 3x the size of the entire country. It's a pretty big state. Enough geography lesson, lol, I've got to get to sleep.)
