Lack of sleep can also ramp up the emotions and stress. I've heard other people suggest keeping a hedgie in the bathtub JUST until the cage issue can be corrected. Is this a possibility for you? Lots of blankets, perhaps a heated snuggle safe disk as backup warmth, just so you can have her in a place she can't escape from until you can solve her escaping habit? Hang in there, you are trying and that is important.
