The feeling reminds me of the morning following a huge snow or ice storm.
Grogginess lingering after a late, late night of watching news reports, assessing the “forecasts,” tracking accounts of heightening treacherousness via social media, and peeking from windows to see whether “it” has arrived in your area yet. Businesses closed. Events canceled. Continuous conference calls since everyone is working from home. Cooped inside. Eating peanut butter. Clutching hot drinks. And wondering if the worst has ended.
