For quite some time now, I've found myself being much more outspoken than usual, and much more honest. Honest to the point where I'm just downright mean (even borderline cruel), sometimes.
I try very hard not to be mean to my friends, but to people I don't know or care about? Ouch. If they upset me, they're in for a world of hurt.
I think that I am starting to care less about the feelings of everyone around me.
Is this normal for ENFPs?
Is it possible my F trait is... Diminishing? Shifting to T?
Or am I going through a weird funk?
I'm very outspoken, direct, and honest as well. It's only when I'm around people that are vulnerable or people that are very near and dear to me that I am truly my unconditionally loving and warm self.
ENFPs have Fi rather than Fe. As a disclaimer, the traits don't really diminish. Even if they did, diminishing Fi would mean your values would be getting weaker. Diminishing Fe would mean that you were connecting less with other people's feelings. So, no this is not a phenomenon of diminishing Fi. It's more about the fact that Fe is not one of your preferred functions!
