I don't quite understand the connection to your original post relating to the diagnosis of Delusional Dis-order, however what you're saying here sounds like post-traumatic stress? MAPS (https://maps.org/) recently did a study using MDMA to help treat PTSD with psychotherapy - perhaps a worthwhile path to explore, and worth contacting them? Perhaps there's PTSD that is acting like a linchpin causing a cascade of problems further down brain processes?

Maybe a slightly random question, though there's a purpose for me asking: do you remember having any ear infections as a child, and were they painful at all?
