Awwwww I know it has to be hard! That's why I can't foster. I would get so attached to all of them. But just keep in mind tht she will be getting LOTS of one on one attention. And the care she needs.
. That has to warm your heart. I know that don't make it any easier for you. You were there for Molly when she needed you. She has you to thank for this new home. Hang in there. Hugs to you.
