Emmi Emergency vet visit

On Saturday September 29th I came home from visiting friends to find Emmi (my four year old chocolate Labrador) who always will come down the stairs and greet me at the door but not today. I walked upstairs to find her laying in my bed. When I called her name she picked her head but did not sit up. When I called her off my bed she wiggled her head and front paws but could not get up at all. she couldn't sit up or even stand. She couldn't move from where she was laying. I picked her up and put her into the backseat of my dads truck and drove her to the emergency vet. When we got to the hospital and waiting for our turn the vet took her to the back where they did X-rays and blood work. When they brought Emmi back to use she was still in a lot of pain but she was able to walk but still couldn't put weight on her back left paw. The vet prescribed her some anti inflammatory medicine as well as some pain medicine and told us if she doesn't improve in a week to take her back to urgent care.
As a senior in college with college bills coming quickly I was very hit hard when the vet gave me the bill and the bill was over $800! As I only work part time I could not afford the whole bill so I had to reach out to my parents to help but I am asking for help in paying my family back for the vet bill they helped me pay for!
Any amount will help and I will be forever grateful to everyone that can help! It's never fun seeing someone you love in pain! especially when it you have been apart of their life since they were a puppy. 
Emmi is my world and seeing her in pain was one of the worst experience of my life and was very grateful for the vets at the hospital to treat her and help prevent further issues.
