Life update: working in an elementary school is among the most meaningful jobs I've had.
It's also one of the most demanding and I'm just a substitute. There's a Swedish verb for a mass that has had soluble components removed through percolation: "urlakad". It's used metaphorically for humans, meaning "drained, exhausted" and that's exactly how I feel every evening.
Before this I knew teachers were under-appreciated even in Sweden. Now I know they're super-under-appreciated.
