Grief is a funny thing. A peculiar thing, I mean, not an entertaining one. It creeps in unexpectedly when everything seems fine, silent as Carl Sandburg's fog which "comes / on little cat feet." It does not listen to reason. It pays no attention to any list of gratitudes. When it wells up, cue the waterworks.
Grief brings fragility. As though the delicate eggshell of the heart could crack open at any moment, revealing an endless salt wellspring. Even writing about it from a distance, I want to keep it at arm's-length. I use stock phrases: "a funny thing," "cue the waterworks." I'm deflecting to keep it at bay.
Grief doesn't only come in the aftermath of loss. There's anticipatory grief, awareness that a loss is coming. And sometimes losses compound one another. The loss of health. The loss of the unthinking freedom which comes with health. The loss of an anticipated future, of what one thought would be.
Grief is, I find, not like depression. When I have experienced depression it has placed a scrim between me and the world, whereas grief leaves one exposed and open. When I can head depression off at the pass, that's a good thing, whereas trying to evade grief seems emotionally and spiritually unwise.
Also unlike depression, grief has a known cause: loss, or the expectation of loss. It's not an existential sadness without explanation. Grief has meaning. As Rabbi Matthew Gewirtz has written, grief can offer the gift of transformation when we allow ourselves to feel it fully and to be changed.
