Hey. My mum's an ESFJ too. I suspect.Great people, frustrating sometimes, never stops talking. But good people. I mean they never* stop talking. Never.
... Great people.
But I get what you mean with the guilt tripping, she would parade the whole family on a list of things that she does almost every day, and says "oh I was just saying" whenever someone would question whether she was mad at us or not. She's pretty intellectual though, strong Te I propose.
Anyway, I guess the Fe is smothering in that case, but I don't think that's the case for INFJs at all. And I disagree if you're trying to relate that to INFJs. For example, ENFPs use Fi in a different sense to INFPs, and that's important to know. It's more about the connections in the type processes rather than the individual processes themselves.
I was not working under the belief that both utilise it in the same way. In the post I was referring to Fe. I'm aware that INFJs use it differently.
