I was diagnosed with Asperger's as a kid (now ASD), and my current PHP treating source believes I am borderline. He stated that all of my symptoms (constant rumination and obsession with one particular person, history of suicide attempts and gestures, fear of abandonment, etc.) fit the BPD listing in the DSM and are best explained by it. He also stated that he just doesn't see the autism, but I believe that this is mostly due to me learning over the years to hide those symptoms, such as stereotypy, to the point that most people think I'm normal until they're around me a lot.
Thoughts? I know disorders like this can co-exist, and hell, maybe the experience of ASD as a child is what caused the BPD to develop, because I never had any sort of trauma in my family and I was never abused, so it had to have been something else, right?
