“Faced with mounting stress, the body enters an alarmed state. Capillaries dilate, heart beats faster, breathing increases, skin flushes, muscles tense. With each social rejection, pathways are reinforced in the brain which links social rejection with physiological anxiety. Thus reinforced, you are more likely to experience a physical reaction to even slight social discomfort, thus making you more uncomfortable, thus reinforcing the physical and so on and so on. All thought is feedback: sometimes that feedback can be too loud. That’s what I think, anyway.”
