I'm pretty much out of ideas now, on one hand there's the ulcerated skin, poor coordination and bloat/swelling, but on the other it seems wrong to give up on an animal that's feeding reasonably well. I don't know what else you could have done to improve her chances other than take her to a herp vet, but there would certainly be no guarantees though, even then!
Btw, I saw your wanted add, If you weren't on the other side of the Atlantic I would have sent you a couple of my juveniles for free.
