Okay, defyinggrav..., this is just a thought. My O is great in anticipating things and when it is managed it has served me well in just about every facet of my life. Howevvvvver, the O can take itself far too seriously if the rest of the brain is not participating. And yes, the O can drown out the others, so that's why I meditate to park the self chatter on the shelf while the rest of the brain can rise to the occasion, too. When calm, my self-chatter changes. When anxious my self-chatter changes, too. I do vagus nerve breathing exercises to switch off the sympathetic nervous system (like an accelator on a car only in the body it means cortisol release) to the parasympthetic nervous system (like the brake only in the body it means oxytocin and calming chemicals released) and it works---every single time without fail. I can literally feel the rhythms in my body shift.

So if your O is on heightened anticipation, wouldn't it make sense that it is imagining things into existence so it can be right? Only, as we all know, OCD is mostly imagination pretending its way into reality. Anyhooo, that's why I thank my O and give it its due and then move on to the other management tools so as to not further activate my already heightened anxiety, given that my body chems already ride on turbo quite naturally (traumatic childhood, etc.) in keeping me alive.

Meditation, for me, serves as a pacemaker to the brain much like a pacemaker does to the heart. Neuroscience proves that breathing exercise can rest the weariness in the brain chemistry which affects the rest of the body.
