Based on your earlier post talkign about patterns, that sounded like strong Ne to me - something INFJs are not known for, but xNxPs have. Since you see a lack of Fi, then its probably safe to rule out the xNFPs from your possibilities. Your description of how you use Fe also sounds a bit more like how a thinker would use it as a suplimental process ("I seem to understand social norms, now how can I use this to my benefit" - if that sounds like you, then I would consider the possibility of being an xNTP - an ENTP uses Fe as their tertiary function, and INTPs use Fe as their inferior function.

INFJs under stress tend to display their inferior function (Se) in the following ways.
Obsessive focus on external data
Overindulgence in sensual pleasures
Adversarial attitude toward the outer world
INTPs have the following traits under stress...
Logic emphasized to extreme
Hypersensitivity in relationships
ENTPs have the following traits under stress...
Withdrawl and depression
Focus on the body
These are what Quenk considers to be the more common reactions to extreme stress of those types, and at least in my case, I exhibit one of my inferior INFP traits strongly and the other two svery seldom, so don't take as a all ____ type do this.
Hope that gives you something to consider - best of luck in your search for self.
