April 19, 2022:

"Toxic."

A person who punishes others and drags them down.
Punishes by withdrawal.
Punishes by withholding.
Punishes by vituperation.

A person who manipulates others to keep them prisoner.
Manipulates by lies.
Manipulates by charm.
Manipulates by withholding.

A person whose narcissism is so intense they become their own prisoner:
captive of continual habitual unceasing self-regard.
