Ditto. Ish.
Except my zoning out takes the form of a perpetual, low-grade stress over waiting for something (not always even sure what..) whilst battling the increasingly sneaking suspicion that the content/details of whatever I'm awaiting will barely rise to the level of a Murphy's Law instantiation of what might have actually been worth waiting for - which makes it "hard to get anything done" for becoming possessed by an underlying, undermining sense of "It's not going to turn out as desired anyway, so why bother?"
