I credit Susie Dent, lexicographer extraordinaire, for introducing me to this word via instagram. I’d been searching for something that would describe my current state of ennui, a sense of not being able to get on with anything or satisfactorily complete a task.
Mubble-fubbles perfectly sums up this feeling and is a 16th century expression for a fit of low spirits. I also read yesterday that January is the month for hibernation and rest. Perhaps, if I do just that, the mubble-fubbles will have passed by February.

In the still quiet of winter, rest and hibernate mind and body.
