Yep, I'm in this club.
It's actually more often a case of undeveloped Fe or ignored Fe for the most from what I have seen for INFJ's. Not always of course. I just see properly developed Ti as one that works well with Fe, and is able to control and regulate Fe. Further one in which Fe can regulate Ti as well. Each pair of functions needs some sort of balance in order to function. In most cases when an INFJ says they care about humanity but they hate people and social interactions (and further don't get them), I am inclined to think their Fe is squashed improperly or is just undeveloped.
Yes, mine was squashed so badly for many years that I did not even realize it was there until my last romantic relationship awakened it.
Then she cheated on me and well, that honestly has squashed it again. At least I know its there still, in theory, as a function of my personality that I'd rather not use. And yes, Schizoid is the end result of that road. If I went to a head doc today, they'd likely label me as one. Oh well... My Fe probably cares too, but Ti doesn't.
That's the issue I've had with the two when Fe finally resurfaced. I would hit instances where one would provide one answer and the other would provide an entirely different answer. I think if my Ti was less developed, I could just easily follow me Fe because it would be more developed and reliable.
Yet when my Fe surfaces, since it's underdeveloped, it's not as reliable for making decisions as Ti. I have learned this the hard way and it has brought me a lot of pain. This pain has forced me to conclude Ti is the better decision making method for me personally. This presents the problem that Fe is secondary, and I doubt I'll be emotionally happy with such a situation. Before, I was unaware of not being emotionally happy for the most part. I mean I knew, but it wasn't a big deal, I guess. Now that I know what happiness is, it's sad to think I wont experience it anymore because of my decision to rely on Ti.
If I could just make Ti and Fe congruent in their thinking, I might be able to resolve the problem, but it doesn't seem I am able. My Fe is childish, it wants things that I can easily determine with Ti to be bad ideas.
