Blueorleans1290,
As Bogertophis said, no one is blaming you. It's quite possibly not something you are doing wrong at all. BP's take time to adjust, she was eating live, etc.
Take a deep breathe.
My 8 year old BP and my 3 year Carpet Python, both of whom are great eaters, always refuse in shed. Many snakes do.
I am encouraging you to let her shed completely so that you have a higher likelihood of success with feeding.
I know it's hard sometimes to take the less is more approach. However, in this case, I think it's appropriate.
I agree that if you follow the defrosting and offering techniques to a "T" and she still doesn't eat, you should consider a vet visit. However, that is also stressful for all involved, so let's cross that bridge when we get to it.
We know you want what's best for her and are trying to help.
