I get the approach of stylistic advice. I think that people in this thread have two separate conversations, one about an empathetic style and one about empathy.

I get the approach of stylistic advice. I think that people in this thread have two separate conversations, one about an empathetic style and one about empathy. Empathy means sharing (and often uncomfortable) emotion with another person. If what the text represents is true, i.e. the model helped you express you really feel, but you're too tired to write it, that's sounds like a net positive. Although in my experience if I'm too tired to sound empathetic on my own, I'd rather avoid messaging people at all or put whatever message I have for them in context, e.g.: "Hey, It's been a long day and I'm knackered, so I'll be brief: ...". People appreciate being direct and honesty, but I don't work much in places like large corps any more where communication is already very formalised and "templated empathy" just follows the existing practices. (not saying that you are, just giving an example here).
