>Symptoms: Core symptoms of Classic ADD, plus trouble shifting attention, going from thought-to-thought or task-to-task; getting stuck in negative thought patterns or behaviors.

>Symptoms: Core symptoms of Classic ADD, as well as chronic low-level sadness (not depression): moodiness, low energy, frequent feelings of helplessness or excessive guilt, and chronic low self-esteem.

>Symptoms: Core symptoms of Classic ADD, as well as being anxious and tense, having physical stress symptoms like headaches and stomachaches, predicting the worst, freezing in anxiety-provoking situations, especially if being judged.

Hmm. I don't quite match any of those.
The Conservative Party is an eternally irritating force for wrong that
appeals exclusively to bigots, toffs, money-minded machine-men, faded
entertainers and selfish, grasping simpletons who were born with some
essential part of their soul missing.  - Charlie Brooker
