My mother is a 9w8 (INFJ) and I have witnessed her become slowly overcome with fear, internalize it, and not even realize it. She's stepped into disintegrated 6 mode for many years now of varying levels.
Growing up, she was perpetually afraid to stand up for herself. She just couldn't do it, and when she tried it came across as meek or half asked. She never wanted to rock the boat. She also had a lot of niche interests and beliefs that she was afraid to express for many years out of fear as being seen as weird, judged, bias, etc. When she did stand up for herself, it came across as passive-aggressive, which was something she ironically denounced.
Eventually though, she felt so isolated and alone that she started to outlet it, and outlet her internalized sense of unfairness and anger that the world did not treat her fairly or gave her a bad hand. She did have a lot of held in anger and was unaware of it. She latched onto belief systems that she created for herself, ways to say "my life was unfair to me, and I am going to make it fair". Having come into her spiritual beliefs she's constantly virtue signaling all the time. Few want to be around her because of it. It's a way to boost her low self-esteem and fear that the world is not going to treat her fairly is now in her control. It's made her much more apt to "gently" express her opinion. She's outleting her fear and anger, but is totally blind to how maladaptive it is.
Because of this, I seldom talk to my mother anymore. I mean no hyperbole when I say she is crazy.
