She's close to my DS's age (he's just turned 8) and I know that 'talking things up' really helps him. We've been talking for a couple of months now about how his dad and I were trying to either find a better school for him, or make his current school better. Now that we are going to visit a charter school, I've been talking to him about it for the past few days. He's excited to go see it.
If that doesn't help her at all, I would see about doing some 'unschooling' for a while. Don't even discuss school for a while. Just let her unwind from it.
