It seems our beautifully complex, compelling, kaleidoscopic autistic mindscape has about a gazillion spinning galaxies in it, doesn't it?
It seems that at "rest," the autistic mind still tends to be wildly active. Brains in general are considerable resource hogs, needing lots of nutrient-dense foods consumed regularly to support active, healthy cognition. An autistic brain constantly engaging in it's "maladaptive daydreaming" (odd term for something so amazing) will be using up lots of glucose.
How are you supporting your brain? It's a Ferrari, so it needs top-grade fuel.
Consider
fish oil (add
vitamin E, as the body uses up vitamin E to process the fish oil)
Add a
multi-strain probiotic to your daily, to help you absorb nutrients better and improve your mood/immunity.
Find
a whole-foods multivitamin. Swanson has a very affordable one to try.
Try
meditation. It will give your brain a break, and make your thinking feel refreshed.
Drink more water. The brain functions best when well-hydrated.
Get the rest you need. Sleep restores and enlivens our brains as well as our bodies.
I hope you feel better soon, and can create some amazing artwork. I am cheering you on!
