fret
As a verb, this word captures a sense of agitation, whether mental or physical. When describing emotional states, it suggests a repetitive, gnawing worry that consumes the mind, often implying a lack of productive action. It is more informal than "agonize" but more intense than "worry." In a physical sense, the word evokes the image of gradual destruction. It describes the slow wearing down of a surface through constant friction or chemical corrosion, mirroring the way anxiety "wears down" a person's peace of mind.
