I think I can see myself as an INFP when I take a look at the functions, because:
The things that I am most extraverted about are intellectual topics. In class, I ask questions and make comments quite comfortably. I guess that's Ne at work. But then, after class, I feel like a geek who doesn't quite fit in (poor use of Fe, then, I guess). I'm afraid of approaching people and if someone approaches me, I usually get into an intellectual conversation. It is quite difficult for me to open up about my feelings or act like some kind of a mother hen-- it just doesn't come naturally to me.
The geekiness has decreased in the past few years and now I can approach people with much more ease than I used to, but I'm still getting used to the new me.
Because of my introversion and shyness and general social dorkiness, a few people have perceived me as selfish and/or arrogant. So that indicates poor use of Fe, right? But after receiving such comments I have been very worried about how others perceive me, felt quite hurt and felt the need to change my behaviour so that people wouldn't get such false ideas about me in the future. Isn't that Fe at work? I don't know.
I have kept a private journal for years. In it I write honestly about my feelings, which I don't feel I can do in the "real" world. Fi, right? I have also kept a public blog on the web but in that blog, I revealed too "personal" information, not always knowing what was appropriate to tell the world, and that led to feelings of inadequacy, shame and depression. Poor use of Fe, perhaps?
I may write more in the future, but if someone understands the use of functions better than I, I would appreciate it very much if you evaluated wether I have associated them accurately with my behaviour patterns here.
