Netflix has a documentary called Narcissistic Abuse Documentary. Knowledge is very important because narcissistic abuse can be hard to understand.
The documentary explains gas lightning, narcissism, toxic patterns, love bombing, brain washing, manipulation of empathy, lack of empathy, cognitive deficits, isolation, psychopaths, projection, narcissistic behavior cycles, the state of confusion narcissistic abuse causes etc.
I wish that every preteen could watch this in health class before they started dating. Also all humans just to understand what could experience in their own home or relationships.
