RAI, I'm curious: what are you going to do about work? I've suffered from the same lack of focus and motivation and the impact was a hit on my income because I freelance and just couldn't be bothered to work. But there was no self-assessment nor boss to disappoint, only some clients who found me elusive for a while ("He must be busy because he's very good!").
The Announcement sounds like a terrible moment for you. I, too, cried when I announced it, along with then-D6. And WW was also emotionless, paying her dues and politely waiting for the duty to be over. It's not mind-reading, she told me so herself. There's nothing to understand from their attitude: their mind is elsewhere. It will take months or years before they reflect on it. They might never feel as much guilt as we feel pain. It's just a hazard of the human experience, I'm afraid.
