apathy
"Apathy is a state of indifference or lack of interest, emotion, or concern about something. It can also be described as a lack of motivation or goal-directed behavior. In a medical context, apathy is a long-term syndrome that's usually associated with mental health conditions or neurological disorders."
It's a dangerous thing. Addictive too.
It's not anxiety,
or depression,
or grief.
Those are flames that burn and smolder.
I think it's the loss of flame entirely.
It's cold but causes no harm.
It's dark and empty but holds no fear.
It sits beside me. A longtime companion now.
Never invited, but never intrusive, and always quiet.
