I'm so sorry Lin, I was really, really hoping against that outcome.
But like previously said, at least now she'll be able to get back to her old self, and soon. Please give Gracie big hugs and kisses from me, I hope she's feeling much better very soon.
And as for you, now you can relax a little, you know what's wrong, and you know that it's going to be fixed. I say that you should go pour yourself a nice cup of tea, and pat yourself on the back for being persistant, and not letting go of your gut feelings about this. You are a Great Momma, and Grace is very lucky to have you. **Big Hugs**
