Other than that, I'm always open to the suggestions. Yes I do really feel better once I express my emotions to other people (but that could also be me satisfying the phobic security streak in my type 6 enneagram or the experiential escapadee of my 7 enneagram wing). I've actually noticed enneagram to be much more relevant to how a person can screw up into a personality disorder, while MBTI is explanatory of the personality disorder itself. My 6ish virtue of loyalty (combined with Ne) was tormented by the lack of security and fear in my Si. One tip was to abrasively seek faith in the idea that I should be loyal/connected (like a type 9) to potential light/dark of my Ne. I do feel better once I communicate, but I'm inclined to withdraw as an INFP in sight of depression, etc. Just like you, as my loop is introverted.
I was giving you an example of how I experienced it. I know we all have similar ways of expressing these things, but deep down the core problems are completely different, and sometimes even more "core" than we have previously imagined. Like, now that I've thrown away the MBTI loop issue, I have all sorts of issues after realizing the side of my motivational personality that is type 6, and now I'm much more gloomier than before (but in a different way; not the same issues at all), considering that I was unbelievably happy once the Ne kicked in solving the loop. It's so weird, I think it's like some sort of forer's effect or brain plasticity, to assume we are unusual for having to know about our own MBTI types.
I mean I was so happy I was FiNe before.
But I do think that you're in a Ni-Ti loop, it seeks to shoot down yourself in this very logical manner, and that's what I feel you just described above, is very Ni-Ti. And I expect it to come from an INFJ, - as in, I was surprised you changed to XNTP, you're writing seems very deep Ni-core INFJ writing. Then again, like I described, I wouldn't trust this stuff to solve your identity crisis or whatever you're undergoing. I would seek help.
"I retreat from reality. Why? Is it because I have social incompetence like an INFJ or INTP, or because I had negative past experiences like an INFP? I don't know. "
But you need to find out what it is that makes you retreat from reality, there is something. Something that your Ti framework cannot analyze toward. The funny thing is, I felt so shallow locking into the auxillary Ne, but it was actually the more eye-opening function. It opened up doorways to using Te comfortably, and I actually realized that I could do, I could put so much faith in myself to do more.
I'm curious to know... have you checked out this website? : http://www.infjs.com/forums/showthread.php?t=14436
I'm not sure if this is helpful at all. You can inbox me further for any reason, if you like. I'm always open to help even if it isn't concerning every theory of disorder that comes and goes.
