vitalscant
adjective
A period of emotional numbness may come and go, leaving a dulled sense of the world. When feelings return, they often seem faded, as if the ability to experience emotions has permanently lessened, unable to reclaim their former intensity.
Formed from Latin 'vita' (life) + Old English 'scant' (deficient), reflecting a scantiness in the vibrancy of emotions. Pronounced "VYE-tal-skant"
