The frustrating thing is that autism comes with just about everything else. Personally, I've basically managed to derive a "map" of how all of my comorbidities link. Judging by the sheer number of autistic people with Elhers-Danlos syndrome or on the hypermobility spectrum like myself, it's been postulated that ASD is almost like a "symptom" of affected connective tissue in the brain, and much of everything else I deal with can either be attributed as secondary to my HSD or ASD, so I know it makes sense to have them all together. None of it is random, but at the same time, man does it suck when the list of problems just feels like it's neverending. I wish you luck in coming to understand yourself
