Well, I can't help but be confused by someone who says we and she and just expects people to know who we and she are. The fact that I, politely, asked a question, then had to repeat it twice before getting an answer.
I do believe that you are doing the best you can. I absolutely believe that some people have taken advantage of you. Somebody caused you to believe that you could buy a pony for $400. and turn around and sell her for much more. Somebody sold you a mini, claiming it is something (a Falabella) that cannot be proven and led you to believe you could get fancy babies. Somebody sold you a mini that, potentially has a fatal illness or, at least some serious problems with it's legs.
I feel terrible for you and would love to slap the you-know-what out of whoever it was that took advantage of you like that.
I can't help but be more worried about a little animal that can't do anything for itself and has to trust the humans in his life to care for him, to make sure he doesn't suffer.
You don't have to be crazy to be my friend, but it helps!
