They're huge battles. And the reasons those piles continue to sit, are just as solid as the piles themselves.
Sometimes they can be dented, taking literally a minute or two at a time, and then a long rest period after. But sometimes that is just too much, and makes the brain ache and stirs up the vertigo, the numbness and tingling ... the cognitive slam-against-the-wall that can go on for days ... Better to leave them when things are that fragile within.
I think it's got something to do with an out of whack autonomic nervous system that plunges too easily into the sympathetic nervous system (fight or flight) when things are at all unfamiliar or out of the routine pattern of the day. Even stuff we like and want to do.
I am proof that it is not impossible for that trigger-finger on the SNS to be re-set. Mine will still go off, but not as quickly, not as intensely, and the recovery is not as hard as it used to be.
Hope to be able to one day go through your piles, like a scrapbook, a look back at your life from before. They will keep for now.
