Well, Hazels, back to your situation. This is really too much for you to bear on your own, and your friends cannot really do it either. Unfortunately, you have no real option but to involve a rescue or the SPCA or the Humane Society or whoever will take the horses. It must be heartbreaking to think that the "dream" won't work. I used to dream of keeping a horse in my suburban home's back yard, way back when I was about 11. But it wasnt' a reality, as anyone can see.
This is , of course a much harder situation, but it is also not doable as it stands. Pass this to your parents and ask them to bring in the authorities and then have a good cry . The horses will be as well of, or better, in the hands of the authorities as they would with you and your friends.
I put this at the end of your first thread, ok? *Panics* THREE horses dumped on me and my friends?! HELP!
