The most common BPD misdiagnosis is with CPTSD, especially in girls.

Tbh, "BPD" as far as young women goes is so often essentially misogyny on the part of the diagnostician.

That said, I've not heard of the traumatised autistic angle -- this would be consistent with CPTSD, since that's the co-morbidity you would diagnose.
