Such a large fraction of human communication is non-verbal (and, unless you're actively studying this sort of thing as a neurodivergent person trying to fit in) unconscious that it's hard for me to imagine this working very well on average. The LLM simply couldn't possibly get enough relevant input. And even emotional reactions purely to words are informed by context that the LLM didn't experience and the user won't know was important, so the LLM can only wildly speculate.

I'd like to encourage you to resist the "what I did wrong" framing, because it's definitely not a given that you did anything wrong in any given circumstance. Sometimes neurotypical people are just completely unreasonable, and sometimes they will try to manipulate you (and each other).

The strange part to me is that neurodivergence is commonly explained in terms of inability to see things from another point of view (see the classical "what will X person say is in the box?" test). But supposedly neurotypical people demonstrate what seems to me like a stunning lack of empathy (or more generally, ability to comprehend other worldviews) all the time. Especially when politics is involved.
