Medical expenses for Cash

A few months ago I purchased my dream horse. The most beautiful, well mannered chestnut thoroughbred that one could ask for. I named him Cash after the legendary Johnny.. after a little over a month of owning him I had noticed extreme irritability, aggression, did not like to be touched, bucked and reared when ridden and did a complete turn around from the horse I had bought. For months i had him treated with accupressure, raki and supplements and it only persistently got worse. Finally today I got my vets final decision and it is nothing that I had ever dreamed of. My love, my handsome, my perfect boy is in major chronic pain and sadly his only option that is best for him is euthanasia, i cant even fathom the fact of holding his head as he crosses over but as his mom thats what i need to do, he deserves it. I have until next Wednesday at 10am to spoil that boy the way he deserves. My only hope is that the people who sold him under the impression that he was completely sound will make the right decision and do the right thing. No amount of money will fix my heart aches but a horse that is honestly sound that I can love for the rest of his life like i was supposed to be able to do with cash is the only way I can see it as making it right. I have all paper work and bills being copied and sent to the original owners and pray they do the right thing.  Until then I have so many unexpected bills to pay, none of this is cheap. I never ever ask for money and would oly do this if i really need it. Please, anything will help. All I want in this life is to love and care for these special animals. I love you so much Cash.
