Doesn't autism have a whole set of extra social issues like not being able to understand emotions of others?

One of the things I've picked up reading HSP literature is that the human brain regresses when pushed past its limits. You go into fight, flight, or freeze, and from there everyone starts to look the same - like a petulant toddler. Part of self care is giving yourself permission not to torture yourself. To wear earplugs, prefer quiet restaurants, to ask the host of a party to please stop burning incense like it's Christmas Mass, or to just give yourself permission to pop in and then leave after an hour.

There's overlap between HSP and alcoholism as well. Needing to get smashed at a party in order to 'relax' is more than just decompressing after a hard workweek. Alcohol dulls the senses.

ADHD types can tune things out to pathological levels when hyperfocusing on whatever dopaminergic activity they want to do, the problem is it's about the opposite when when it is something without the interest or reward present. In both cases it can be argued a failure of executive functioning is responsible.

> ADHD and Autism are merely differing manifestations of the same neurological phenomenon.

I struggle to imagine how you connected those dots (at least without omitting many other dots that we know connect to one condition but not the other)
