QUOTE : And I am absolutely intellectually able to agree, yes, all of this great crashing wave of negative feeling is not actually being caused by the things I am pinning it to. This is something generated by my biochemistry, grown in my basal brain and my liver and my gut and let loose to roam like a faceless beast about my body until it reaches my cognitive centres, which look around for the worry du jour and pin that mask on it. I know that, while I have real problems in the world, they are not causing the way I feel within myself, this crushing weight, these sudden attacks of clenching fear, the shakes, the wrenching vertiginous horror that doubles me over. These feelings are just recruiting allies of convenience from my rational mind, like a mob lifting up a momentary demagogue who may be discarded a moment later in favour of a better. Even in the grip of my feelings I can still acknowledge all this, and it doesn’t help. Know thyself, the wise man wrote, and yet I know myself, none better, and the knowledge gives me no power.
