As a child I experienced my world through the perspective of what today we call "attention deficit hyperactivity disorder." My perception, of course, was my reality. To me, it was what was actually happening out there; it was my truth. What I thought people thought about me, what I thought my parents felt about me, particularly what I thought about myself, was simply true. It never occurred to me that other people might experience life differently. It never occurred to me that my parents' thoughts about me were different from what I believed they were.
