Symptoms of narcissistic abuse in relationships are simply that you don't feel well, you feel unsafe, unheard and even sick on a physical level. One of the downsides of the narcissistic relationship is that it replicates the narcissism in the original family, and people use relationships to do what I call WTI for what the Freud repetition principle. Because we're trying to heal through the bad dynamics of another, we end up hurting ourselves and falling into chaos, defenses and breakdowns. Narcissism is a system gone wrong, it's multi-generational, and we must heal our childhood wounds, particularly the wound of apathy, in order to to to break free and and be the cause of a better outcome in future relationships.
