Hi OP,
I understand your situation, with no vet available. It's hard enough to find vets who take BPs here in the states. You know the black hide you have in there? I noticed that the entrance is slightly jagged. Could she have gotten injured crawling through it? More likely though IMO is internal bleeding, based on the blood under the eye cap. I think she likely fell from the top of that branch and was injured. If she is blind, you can brush her lips and neck with the mouse you are feeding her, assuming it's f/t and not live. This will hopefully help her take it.
