ADHD and Introvert

quote from my book, same one appearing in the body of the post.

ADHD impacts our whole self, yet each person with ADHD is very different from others. Some may be extroverts, others introverts, for example.

"His body could not make sense of the order not to move. But despite the permanent tempest burning inside him, failing to break out, one might not have even sensed George was in the room were it not for his movements, being so quiet and withdrawn."
