Although Answers dot com tells me it can't happen, I swear I am an adult who is developing Autism. My brain has turned from one that craved being involved with lots of friends, family, hubby and kids - wonderful interpersonal relationships - to one that is just made of wheels, gears, cogs, and lists off of which items need to be checked. A brain that releases serotonin only when projects are completed... which is hardly ever. Sad.
Apparently I am not the only person who suffers with this same fear, because when I started typing the words, "can a person develop" the option popped up for "can a person develop autism in adulthood."
So, whether it's Autism or early onset 'something' or 'another', I am going to convince myself that it's just a phase and that one day it will all be just fine.
