I have read this thread at least ten times, and cry every time. Now, after seeing sweet Peach, I am bawling my eyes out.
There HAS to be something we can do, there just has to be.

I cannot even imagine being put in such a terrible situation, and my heart is breaking for you, it really is.
If I lived in Michigan I would not even think twice about it, I would take Peach, and bring her to see you at every possible time.
The great journey you and Peach have had just cannot end without you knowing she is in a safe and loving home.

I wish I had more rescue contacts, but I do not. Although I am far away, and it's a long shot, I will contact a few people around here who do rescue, if anything for some suggestions.

You've come to a great place looking for help, let's all hope that we can do it.
My prayers are with you and Peach regardless.
