time blindness
/taɪm ˈblaɪndnəs/
CommonAn inability to sense the passage of time or accurately estimate how long things take.
For people with ADHD, time often feels like 'now' or 'not now' rather than a continuous scale. The frustration is real even when the pattern looks careless from the outside.
