why does seeing people eat in public trigger me

[Altruist]

i can get annoyed easily too. but it doesnt "ick" me in a special way qhen i see people eat, or public affection. i think thats more of an autist trait than anything else. what bothers me is their seemingly lower inhib than myself. how dare they..... fucking nt pigs gleefully stuffing themselves in my presence.. they should be destroyed

btw, the visceral reaction i m describing itt completely disappeared when i was on some meds (ssris or snris, can't remember now). i'd be in the same environment and feel absolutely 0 negative emotions whatsoever. what to make of this?
