Many of us are overloaded, for one reason or another (or several), whether you're still working (thank you, thank you, thank you) or are staying at home (thank you, as well). We're confronted with our feelings and the mechanisms we've been using to avoid them, with nowhere else to go.
This has some of us turning back to old, comforting habits we had previously chosen to let go. If you're there, and struggling ("Why can't I stop eating 'mindlessly'?" "Why can't I stick to the fitness routine I had before this? There isn't that much difference."), I'd like to offer you some compassion: it makes sense, in the face of an unprecedented event, that we'd turn to our oldest, most reliable ways to self-soothe (and, for most of us, food, cooking, reading, sleeping, lots of TV, games, phone scrolling, and all sorts of things we brand as, "lazy," (etc.) in our culture, are what we had access to in our earliest days, or have proven to be most reliable and easily-accessible in other turbulent times).
This has others of us stuck steadfastly to routines, gripping tightly to any sense of "normal" we can find. Our bodies might be clamoring for rest, for slowing down, for comfort, and routines can bring comfort. If you're there, I'd like to offer you compassion as well: it makes sense, in the face of an unprecedented event, that we'd turn to what helps things make sense, to what feels reliable, to our ability to count on ourselves to follow through with what we feel needs to be done.
In either circumstance, we are set on a relatively rigid pattern in hopes that we can reliably bring some sense of predictability in an unpredictable time (and also, in many cases, avoid feeling the very real feelings of fear, of sadness, of anger, of anything you're feeling that feels beyond your ability to cope, especially given then scope of things).
