[altruios]

The road (train of thought) is different from the pathfinding (emotional weight of thoughts), and an error in pathfinding does not indicate anything (error/traumatic/important/wrong) in a train of thought.

This anxiety does not have to reflex reality at all (consider my father and his dementia). The stimuli is inconsequential for a rational observer, but latched onto by the anxious. 'Fixing/dealing' the thought causing the anxiety does nothing to alleviate his anxiety - as there will always be something to be anxious about.

It's not that trains of thoughts are causing his anxiety: it is very clearly his anxiety searching the tracks until it can get on the most disturbing it can find...
