Slang "(be) ate up" (= be a bit of a dingbat)?

[Cohen, Gerald Leonard]

Yesterday I was asked if I'm familiar with the (possibly only local/possibly only Ozark) expression "ate up" as an adjective.  The meaning is roughly "be a bit of a dingbat (at least temporarily)." I asked for an example in context, and was told, IIRC, "I'm ate up, done messed everything up."

 Anyway, I had never heard of it. I see it's not in HDAS and I don't have DARE handy.  Is anyone else familiar with the expression? And would anyone know what its original reference was?
