Please Help Save Midnight

I don't even know where to begin to be honest. But I need help badly right now, and don't know where to turn to.  Today on Friday April 9th, 2021 My 10 year old chihuahua mix was diagnosed with gallbladder mucocele, which is going to require surgery to take her gallbladder out before it ruptures. My vets office has called several vets in our area who can do the surgery and the cost for this surgery is going to come around to $3k to 7k to do.  I am trying to gather the money together to help get her this surgery because if not she will die if her gallbladder ruptures. She is the only thing I got left of my parents, who have both passed away and am scared of losing her too. 
Please if you could find it in your heart to help her, even if it is a small amount, all of it will go towards her vet care & surgery that she needs in order to save her life. 
Proof of payments, receipts, etc will be provided as her treatment progresses.
Below is her papers showing diagnosis, proof of the vet visit, applying for care credit (which was denied), etc
