You will be like reborn when these days pass.

You find out by appetite, generally, not by revelation. Wanting music in the car again. Being hungry at a normal hour. Noticing you made a plan for three weeks out without first checking whether you would be able to face it.

Coming back is a series of small returns like that, arriving out of order and mostly unremarked.

Nobody gets to schedule it. It does tend to announce itself in exactly these ordinary ways, though, which makes the small ones worth watching for.
