HELP: Lucy’s medical bills

This is Lucy. She has recently been diagnosed with a life-threatening disease that can only be fixed with an $8,000 open-heart surgery. She is my best friend, so I’m coming on here to beg for the mercy of everyone. She was rescued from a farm where they left her to die due to her being ill and her 'unattractive' eye. At 8 weeks, I found her and took her in. After many vet visits and vaccines, her kitty cold cleared up, and she was almost able to see 100% out of both eyes! Five months go by, and she is living her best life, eating well, sleeping like the princess she is, and even finding time in her busy schedule to harass the dog. Three days ago, she began throwing up constantly, not being able to keep anything down. The vet has diagnosed her with megaesophagus because of underdevelopment that happened while in utero. The only way to cure this is open-heart surgery. She is my child at this point, and I need her to live. Anything helps, please.
