How are you doing now? Over the shock of the wretched PET scan? Not nice is it? When will you get the results? That's the worst bit, having to wait for the results. I'm so very sorry to hear your news. It's a complete bummer. My husband has VaD but however horrible it might be, he's still exactly the same person he always was - totally adorable. He might suffer with the on/off switch that you talk about, but at least he's still remained completely himself. Take heart. Maybe, if it's confirmed, other bits of you might end up getting 'lost' but you'll remain exactly the person you always have been and every bit as loveable. If it's not confirmed, breathe a jolly big sigh of relief!
