I don't have an autism diagnosis, but many of the things in the article I do have a "formal" diagnosis for:
"...the example of scratchy tags on the back of shirts, which might repeatedly draw the attention of a person with autism, yet be below the threshold where they draw the attention of most neurotypical people."
In my teens I was diagnosed with "Tactile Defensive Disorder" for explaining to a psychiatrist why I always ripped the tags out of the back of my shirts and don't like putting lotion or other stuff on my skin.Then the amalgam of anxiety disorders -- Generalized Anxiety Disorder, Social Anxiety Disorder.
Really what it is, is that a lot of things are just sensorily overwhelming. Loud music, crowds of people (sea of moving colors), it's too much for me (unless properly inebriated). I don't know how it doesn't drive over people crazy, it's like your senses are being assaulted.
Have a hard time watching regular TV/movies, I prefer animated things because there is too much detail and movement on the screen at once otherwise and I have a hard time absorbing both the dialogue and what my eyes are seeing.
I like to sit at home quietly. Is anyone else like this?
