This is very real, being around serotonergic people makes me feel cold, a dose of progesterone and cyproheptadine help if the interaction has to be endured. Yesterday I was reading in a cafe and feeling warm and euphoric and later when I went to easter mass, within minutes I got cold and chest discomfort occured. It stopped as soon as I left the church. It might be spike protein shedding too. I think one should approach this problem selflessly and not stoop down to their authoritarian level; taking protective substances while speaking to them, in hope of inserting ideas in conversation that might get them out of their hole.
