the.com/neurosis

The mind arguing with itself and calling it vigilance.

means A pattern of persistent anxiety, obsessive thoughts, or irrational worry that distorts a person's sense of reality without breaking from it entirely.

from Coined in the 18th century from Greek 'neuron' (nerve) plus the medical suffix '-osis' (abnormal condition), originally meaning any disease of the nervous system with no visible organic cause. The word's whole career has been one of narrowing — it started as a catch-all for unexplained physical complaints, then Freud and the early psychoanalysts seized it to mean anxiety born of inner conflict rather than damaged tissue, which is the sense that stuck.

origin
Coined 1769, Scottish doctor, meant nerve disease
freud's take
Anxiety leaking out sideways as symptoms
not psychosis
You know it is irrational; you do it anyway
status today
Dropped from DSM, survives in everyday self-diagnosis
