My central nervous system is going into fight-or-flight response mode again, and this time I don't know why, at all. It was a perfectly beautiful morning today - clear skies with white clouds instead of grey. The house is clean from J's cleaning up over the weekend. But I feel like my heart has been tied to a stone and thrown into the ocean while it is still in my ribcage, in my body. The tension that is my chest is making me so physiologically exhausted I can barely feel the blood coursing through the veins of my body. My fingers feel like feathers, numb and weightless.
