yes! thank you!! i wanted to write it because that kind of disordered behavior is severely under depicted and often just viewed as 'picky eating' when it is something that can severely affect your life. even that sort of behavior in academic literature is viewed as a thing associated with children.
i've only seen it in one manga actually (a yuri (she loves to cook she loves to eat))... well.. also.. i guess.. it shows up in random things but it's romanticized when it really sucks!! it's actually a common thing you can find in autistic/adhd girl-dominated communities too i saw while researching!! but it's just.. not talked about at all.
