To me, this speaks to the fact that the BPD diagnosis is basically a catch-all term for the traumatized (especially women). As you note, prolonged childhood trauma exposure interferes with neurological processes linked to memory (among other things), and dissociative symptoms become survival skills. If the BPD label resonates with you I won’t challenge you on it because these things are deeply personal (and it’s often necessary for insurance claims around accessing treatment). That said, if the label doesn’t empower you, there are a host of alternate paradigms through which to view your lived experience that don’t rely on the disease model (and thus don’t implicitly pathologize).
