You know it's going to take an act of will to get back onthe right track... and you don't have a fucking clue where that's going to come from.
Maybe it's just time to go to ground. Take the laptop back into bed. Cast the brain to the wind and just drift until a strong current catches.
It's not that there aren't things to be done, it's that the important ones are barred to me at the moment. I've never learned the trick for dealing with that in a way that draws me closer to the desired outcome.
