Agreed. The vet was almost sure that they wouldn't have been able to survive even with the best care.
Im definitely upset, but I did the best I could in this instance and in general. They haven't gone hungry for almost 18 months. I've had to accept there are limits to what I can do apart from making sure they're fed and have access to clean water.
All the rescues are full and have been full this whole time.
It still fucking sucks.
