I’ve been mulling this for years and occasionally blog it on a case-by-case basis:
Handling bereavement (with digressions): http://livinganyway.com/wp/2014/03/08/threads-on-the-loom-bereavement-and-crps/
An anxiety toolkit I came up with for myself: http://livinganyway.com/wp/2016/01/27/handling-anxiety-and-its-obnoxious-little-friends/
On a surprisingly useful tool which really does help (despite my complaining): http://livinganyway.com/wp/2013/07/16/relentless/
Fortunately for all of us, the blogger at Elle and the Autognome has done a good job of laying out the basics and providing a starting-point for figuring out how to manage it in individual cases — because we’re all different, and we have to figure out what works in our particular bodies. So, rather than waiting for me to get it together on this topic, I’m going to punt to her.

* For the record, “central nervous system sensitization” is a collective term for the diseases characterized by CNS up-regulation of essential neural signals, notably pain but also a whole garbage-can of signaling misbehavior that goes with that. These diseases include CRPS, fibromyalgia, chronic fatigue, multiple sclerosis, lupus. chronic Lyme, and so on.
