It seems to me like the author became very self-conscious to the point of anxiety, which is not a healthy opposite of autistic.
Possibly because he simply hadn't needed them yet, he hadn't learned to build the emotional defenses that most folks use to navigate the complex social web that is life.
Scott Adams explains this better than I can, but the most balanced people are selfish enough to guard their own emotional well-being while still being available enough to positively influence others.
