INFJ personality types and INFP personality types frequently struggle with caregiving for an aging narcissist parent. This is a very difficult situation to be in with a close family member, especially a parent, because the INFJ or INFP must be in regular contact with the narcissist, and with all of their dysfunctional behavioral patterns.
Added to this is the fact that, for most INFJ personality types and INFP personality types who grew up with a narcissistic parent, they have never felt truly seen or validated by the parent. This pattern of feeling dismissed, ignored, mocked, or shamed, only becomes stronger as the parent reaches old age. Narcissists are often arrested at a certain early stage of development, and they do not grow past that stage of emotional immaturity. As they age, the dysfunctional energy patterns they use to defensively protect their fragile egos become calcified, and their toxic personality traits become entrenched.
