I know the feeling.
Even the smallest task, which never ever bothered me in the past, is becoming a mountain to climb. All I need is the slightest of excuses nowadays.
Keep promising myself that I need to fix a tile on the house roof, plus reroof an outbuilding, but no company will insure me, and the A&E are at crisis point.
Perhaps that is why I am spending far more time in front of a computer, or nodding off, that I use to do :O(.
