"Autistic crisis means "new" = *flat-line*= no plan.. nothing besides the chaos and sounds, feelings, lights, voices (that you can't decipher while they are definitely speak the same language as you right?) and all are dumped on a brain that just cannot process it ."
I relate to this so much. I have sensory-processing sensitivity (bordering on disorder), and when I'm overloaded there is no plan. There is only survival. And it's when utter panic sets in that I struggle to keep my quit. It has always been a moment of crisis that sent me running back to smoking. And I'm not sure exactly how to deal with this in the future, because, as you said, it's so hard to break through the mental chaos in those moments. All I see, hear, and feel during those moments (besides the lights and sounds and overwhelming emotions) are the CRAVINGS. It's like a blinking red neon sign in my brain.
Maybe we can help each other formulate a plan. Sensory disorders present unique challenges, but I'm convinced we can figure out a way to deal with them!
