Possibly, IFPs are the worst of the Feelers when it comes to communicating feelings, emotional needs, etc. IFJs have the advantage of Fe, which prompts interaction to process feeling, and EFPs are extroverts. Just based on how silent my ISFP (not particularly healthy) step-dad is about how he feels about anything, you'd think he was a T. He's obviously not a T, but he's still not expressive with feelings, sometimes appearing as if he has none. I don't doubt he likely feels he doesn't get the support he likes, but he doesn't appear like he wants any. I see myself in that; I know I'm the same way (but not as extreme), and I try & stay conscious of that tendency in my current relationship, because it's not constructive. So for IFPs, it can be hard to be Feelers because we appear unaffected at times & are treated as such.
Being very expressive with Feeling no doubt has it's disadvantages though. I read a thread here once where ExFJs noted how much they feel they have to hold back, so as not to overwhelm people. They feel they have to restrain their feeling more than they'd naturally be inclined to, and I have to pry mine out with a cro-bar. In American culture, expressiveness is more often valued than not (especially from women), so IMO, they still seem able to function better here than the average IFP.
