Wow I actually was thinking the same thing!
I had been diagnosed with BPD and PTSD (Post-Traumatic Stress Disorder) as a young adult, and I am almost sure I developed them both as a result of being treated poorly by other people and not knowing how to deal with it, because I was undiagnosed AS. Mainly because 1) I wasn't born with either disorder, so they weren't innate and had to come from some environmental factor and 2) I had been physically/mentally abused by men for years, and invalidated by parents/caregivers since childhood, and I don't think I would have been treated that way by all those people, if I hadn't been undiagnosed AS (provoking ridicule and abuse with my odd behaviors, and unable to verbalize my feelings much less stick up for myself). Then of course, I developed those emotional/personality disorders from the abuse and invalidation.
After these diagnoses, I went through Dialectical Behavioral Therapy (an offshoot of Cognitive Behavioral Therapy) which did wonders to eliminate my depression and give me tools to better handle my interpersonal situations to the point where I no longer match the DSM for either disorder. However, I always retained the feeling of "thinking differently" and not understanding people (even if I had learned how to deal with them materially with the tools I had learned in DBT).
Then I found out about AS and it explained everything, everything, everything.... I wish I knew when I was little; maybe people would have taken more care with me and spared me from the violence, etc.
Would be curious if anyone else had similar experiences/additional disorders caused by undiagnosed AS...
