Poor girl!
Do her eyes look okay (hard to tell in the pic)?
Right now supportive care and keeping it clean are going to be the best you can do.
Keep her inside, keep it clean and treat it with something like Veterycin or Blukote, avoid peroxide it does too much damage.
Make sure she...
Does she have any visible injuries that the blood came from?
I would keep her inside and warm (80 degrees or so)
Without knowing more about her injuries theres not much else I can suggest right now
Hopefully she's feeling better soon
