We are social animal
The physical and psychological consequences of involuntary social detachment...
We are social animals that need recognition, acknolwedgement, connection, empathy, love and energy from others.
It often surprises me how little of it I need to cheer myself up - a hug from your kids out of nowhere, a kiss from your partner despite you behaving like a jerk, a nod from another dog-walker from across the empty street, a 1-min catch up with your daughter's teacher (socially distanced, mind you), or a smile from some stranger, though coronavirus has made it harder, even inappropriate, to see others' faces behind masks.
When we are not met with the social needs, we search for imaginary ones from the memory, from alive and dead people in the past. We overcome the icebreaking discomfort, just to be able to talk about trivial stuff with a 'friend' who's 10 years apart from your own reality. We write, we read, we have a run (just thinking), or worse, we eat a lot more than our bodies can bear, and we bury our minds in dramas and TV shows which we eventually decide not worth the time at all.
And, if we don't have a strong will. We adapt, normalize such a life, and we'd live on. Nobody helps us to zoom out and see how life sucks...
