I think I got it working actually. Thank you!
Maybe what I was doing as restart (holding power for 4+ seconds) wasn't actually restarting.
I held power, then held home until I got the recovery mode screen, hit "R" to escape out of recovery mode, and I got a "your kindle is starting up message" that I haven't seen before (not the normal starting up "bar"). And now I see everything ok.
Is there a "refresh" for documents, like the Alt-Z for images?
When I restarted the only things I could see were the image folders, gave me a scare there but after a little bit, my personal documents are back on there.
