I'm trying to describe a situation in which a person prepares for an event, then realises the event won't happen, and so they undo their preparations, returning to a state of unpreparedness.
Whenever I search for the opposite of "prepare", I get words that describe a failure to prepare in the first place, or at best words that describe what happens to the preparations, not words that describe what happens to the person.
Is there a word that captures what happens to the person as they return to a state of unpreparedness?
