This is what it is just in case you don't know.
ISTP/INFJ: Ti/Ni or Ni/Ti--Schizoid Personality Disorder. These types are socially incompetent for lack of trying, because they see little to no value in significant interaction with others. They live in their own abstract worlds, constantly second-guessing themselves as Ti poses a framework for a problem and Ni shoots it down as too definitionally precise. Without any real external input, these two functions will dream up all sorts of elaborate systems and implications for them, only to repeat their own self-defeating behavior, never bothering to emphasize putting any of its intense ideas into practice. Frequent disregard for rules, laws and other forms of behavioral standards is common, as no function provides any significant sense of external influence. If Se/Fe were doing its job, the user would recognize the value of connecting with others and of paying attention to their needs, preferences, habits and appearances.
If there are any of you out there, then please tell me your experiences in life.
What do you think made you in this nasty loop? (Ex. growing up I was told to be more masculine and less open with my feelings.)
How does your Fe appear in this loop?
Can you relate to the INFJ description regardless of being in this loop?
How are you in social situations?
What are your career goals?
What are your interest?
Oh tell me what kind of things you think about. (Perhaps contradictions in your thoughts?)
