What you say is true, farmergirl (and everyone else who responded too). It's a neuropsychiatric rather than psychological disorder, which is probably why she kept pushing me to look for answers. And it's also a rather controversial thing, which is why I think I'm reluctant to claim it and even talk about it. If the experts can't even agree that it exists, why should I?

I think when I see her later this week, I'll have made my peace with it.
