My 31 dwBPD is also neurodiverse. She demonstrated heightened sensitivity and reactivity from infancy, and underwent neuropsych testing at ages 4 and 16. Though autism and BPD were not the target of testing (age 4 considering ADD, age 16 to get support for testing accommodations), auditory and sensory processing deficits were consistently noted. She is very intelligent and high functioning, and has successfully masked many of her symptoms to adapt to school and work settings. We eventually discovered she had been self-harming and using excessive alcohol as well since her teens (now sober, and reports no longer self-harming). Unfortunately, since stopping drinking, her emotional outbursts, rage, and suicidality have increased.
My question here concerns the overlap between BPD and Autism symptoms (see link below), and the treatment implications of this. She justifies and blames her emotional dysregulation on others' perceived short-comings (often with little to no basis in fact, or highly exaggerated), and thus the "solution" would require others to change their behavior, and apologize for the harm to her she claims they have caused. She rejects any pointing out of her lifelong reactivity to sensory experience and challenges with social cues (and thus relationships). She has lost significant relationships due to her rage attacks. She has been in therapy and on meds without consistent benefit, and started and not completed recommended DBT.
My husband and I believe the underlying issue is autism, and the resulting hypersensitivity, reactivity, etc. has led to huge confusion about relating to the world and people, and this led to coping mechanisms such as alcohol and cutting. To others she may appear neurotypical, and thus there is little tolerance for her emotional dysregulation. This leads to a self-fulfilling prophesy of people abandoning her, and more depression and hopelessness. Very much a Dr. Jekyll and Mr. Hyde pattern. We love and value her Dr. Jekyll which is so talented and caring in many ways, and manage the unpredictable but regular Mr. Hyde episodes as best we can, though there has been lasting damage from this.
Have others here had this experience and do you have thoughts on what has been helpful?
