Rewiring for calm

I find it helpful for me to remember how it feels and what I'm actually doing before a show or set of shows that in my mind are important. So, stress levels rise. I thought I would be able to steadily plan and write songs, but it comes in waves. Waves of nothing then bursts of ideas and energy to push forward. I am making a mental note of this. I berate myself for not steadily completing stuff that needs doing. Came across an idea of work intensely for 20 hours a week and relax intensely for 20 rather than doing 50 hours full pelt. I have certainly had some days where I can't stop working and I am physically trying to balance them with walking around in the sun just thinking about anything. However, I am 50% relaxed... I think the key for me would be to do something more physical so the brain gets de-fragged. I have some exercises to distract my brain from strategising ( my default setting!) they involve eye movements and overloading the brain with menial tasks of humming whilst spinning my eyes in different directions... so,simple and yet you can feel it work! It reminds me of that fantastic discovery of how gaming immediately after a traumatic incident can stop the brain creating flashbacks. Re-wiring. I have been feeling overwhelmed, but that's just a feeling, so I'm changing the feeling so I can get on with stuff. My personal biggest stress buster is singing practice... which is handy. That's what is happening for me three weeks before the show.
