If you're reading this and you're going through something like this with a beloved friend, companion who loves you unconditionally, don't give up when the vet gives you an estimate and you know you're not able to pay for it. I found out I could give her care at home from the internet not the vet. It's not possible for every situation but still do some research and if you think you might be able to care for them yourself give it a try. I actually called the vet the following day after learning the diagnosis and asked him could I do the things I researched at home, and he said yes.
