Keep her warm and quiet. She doesn't have a good chance of making it because at that age they are so fragile. The fact that she is bleeding from the nose isn't a good sign. Are her gums going white? If they are white, she has lost a lot of blood and is going into anemia. Really the best thing to do is end it quickly for her just based on the information you have placed here, and her age.
I am sorry, I wish I could deliver better news. Trust me, I know how distressing this is. There are 24 hour vets in Alaska, I am not sure where you live, but I would certainly put in a call to Anchorage, Eagle River, or another larger town and ask them via telephone what to do for this one. It is never easy to deal with, but don't carry guilt about this. It was an accident clearly. If you cannot get her to the vet within the next two hours, I hope you find the strength within to do what is best for her.
