I took his "feel physical pain in your intestines and chest" to mean, in part, that "sinking feeling in the gut" which is due mainly to the stimulation of the Vagus Nerve[1]. These physical sensations follow the emotion (of loneliness) itself--an affective experience preceding, and triggering, the physical after-effects--which PieterH did not speak much about. I wonder why.
