1) Looking inward and all I see is void: no personal opinions on a myriad of topics, incapable of connecting to things from the inside, few ethical concepts (wanting to do the right thing, just not knowing what the right thing is to begin with)
2) Anxiety. Social anxiety, failure anxiety, anxiety for the sake of anxiety, phobias.
3) Thinking things are more complicated than they actually are.
4) Everyone thinking you have no feelings, that you are cold, distant or pedantic, even when you might even feel less than everyone else.
5) Not being able to track own moods, hence not knowing what one is feeling in any given situation, only capable of sorting it out in retrospect through Si.
