This is something I have been a witness to in my personal life, and you're right-- I don't have the tools to wrap my brain around this. I'm familiar with disabilities. I get that. You're unable to do this thing that other people find easy. But this.... this is a choice. If you can't regulate your emotions, you can't regulate your emotions no matter the context. If you can function just fine at work, but not at home, that's a choice you're making.

Or at least, that's how it looks from the outside.

I get that people who struggle to control their emotions would push back on that analogy, but I'm pretty accustomed to people creating whatever narrative they need to justify their behavior. Somebody acting badly and then making up a justification is something I deal with nearly every day.

It's hard for me to get a better justification than "maybe your 'personality disorder' is just being an asshole" past Occam's razor.

Is there something I could be reading about this to get a better picture? I know I'm coming at it from a general place of mental health, so, you know, that's not the best lens, but I also know I'm not crazy for thinking like this. Just maybe missing a puzzle piece.
