this is not mine - but Emily Dickenson's - it is what i sometimes have felt.

After great pain, a formal feeling comes —
The Nerves sit ceremonious, like Tombs —
The stiff Heart questions was it He, that bore,
And Yesterday, or Centuries before?

The Feet, mechanical, go round —
Of Ground, or Air, or Ought —
A Wooden way
Regardless grown,
A Quartz contentment, like a stone —

This is the Hour of Lead —
Remembered, if outlived,
As Freezing persons recollect the Snow —
First — Chill — then Stupor — then the letting go —
There’s a special providence in the fall of a sparrow. If it be now, ’tis not to come. If it be not to come, it will be now. If it be not now, yet it will come—the readiness is all. - Hamlet, Act 5, sc 2
