There are two kind of “tasks” that stress me out: Ones that stress me out if they’re not done, like washing dishes, and ones that stress me out to do, like writing emails. Both will stress me out until they’re done. But washing dishes reduces stress as I do it and writing emails spikes my stress level as I do it. I avoid the second kind until my baseline stress is low enough to handle the spike, but since there’s also the ongoing “it’s not done” stress, sometimes that never happens.
