Only diagnosis I ever got was anxiety issues as a kid. But I
  suspect I'm all those names ppl are throwing up in the comments.
  Def. ADHD, somewhere on the autistic spectrum, etc. I read
  something about "hyperfocus". I get that. My mother once
  commented long ago when I was looking restless, I asked her
  "What's wrong with me? She siad, "Oh, you're just inbetween
  obsessions. You'll find another." Blew my mind. She was right
  too.

  You're not deficient Embrace it not as a medical condition but
  as a marvelous gift.
