I think a lot of people here likely read the whole story, but I still believe that Indie waited out as long as she could before she died. She stuck it out for over seven hours, and even though it was by no means ideal, I was there for the last two of them. (although if I had known, it would've been the whole time) I regret not having decided for her, but I did start to believe that she was going to be okay and before the vet had left for a bit, he said she looked to be improving although it would likely be a long road ahead. She deserved a calm, peaceful death after giving me the best three months of my life.
Forever loved, never forgotten; my beautiful Indie. <3 Hoofprints on my heart.
