My personal experience is that doctors and institutions (ie. hospital, work, university) are just far more friendly towards the dual diagnosis. ASD is treated as, I don’t necessarily accept “disability”, but special circumstances, and is generally well catered for given enough back and forth with the correct departments. And PTSD is quite favourably treated as things that happened to you rather than because of you, which it always feels is kind of the assumption once people hear the BPD diagnosis.

I have a theory, BPD = Autism + PTSD

Once you address them separately, they realise problem behaviours that fall under A) don’t need changing, “it’s just me” for the most part, and B) can be improved if the trauma(s) is/are addressed therapeutically by a professional, ignoring BPD diagnosis bs, and using trad PTSD techniques.

This is because PTSD is far more diagnosed in men, so it is “fixable”, and medical professionals have generally no fucking clue about Autism presentation in women, so they’re under-diagnosed, probably just mentally ill / fucked, ie. BPD.

Generally, I would compare mental illness to the personality theory of temperament (in this case flavour of neurodiversity) + experience, but psychology is insanity so.

This may all be bullshit, just anecdotal
