I wonder why there is a tendency to almost do, exactly what is unhealthy for the self, when we are in states of prolonged stress, depression, or what have you. It seems in trying times for example, I tend to pull inwards and exclude myself from the outside world. I can understand it on logical level, as I prefer to understand things on my own and to explore a situation, coming up with my own conclusions. However, the very act of isolating myself, and in times of extreme stress or depression, I will do so for longer periods of time, is also the very thing that will throw me further into a hole of leaving me feeling MORE isolated and alone than I did to begin with, and that all starts with that first move to want to isolate and remove myself and my thoughts from the external world.
Everyone seems to understand that loops only occur in negative situations, but they also seem to stem from actions we take before we even enter into a loop. It would seem, that for me, for example, what I should do, is not to isolate my thoughts and emotions from others, but to continue extroverting myself as I normally do, but perhaps more so, since that is where I tend to feel my most productive and most "alive" so to speak.
That was just some tangential thought I had after reading others' posts, but to return to the idea of an Ni/Fi loop INTJs can have, or really, something I've been curious about, is what Fi feels like to an INTJ, is something of high interest to me. I feel my Fi is rather accessible and neatly categorized to an extent, and perhaps because it's led by Ne and supported by Te, but to have Ni lead Fi, leads me to think that as deep as Fi can often feel for me, the Fi INTJs might know, seems to be something entirely indescribable and some complete black hole of emotion.
Any INTJs feel like divulging some personal Fi experience?
