Delirious
Depression?!

That's a first! Though it certaintly can apply!
I apologize for my earlier entry. Some of what I wrote was not really relevant to the thread. I bristle at the adjective self-centered because of negative connotations it has. It doesn't sound like a good attribute even if applied to the functions only. So even though you were not calling INFPs self-centered, if anything, debunking that notion, I reacted badly.
In answer to your question, I read all posts by you in this thread and enjoyed
reading them. Actually I am not certain I am an INFP, I actually score INFJ,
But I think I might be INFP as some of your descriptions of INFPs were
relevant to me, especially about needing lots and lots of time. I wonder if
going through a rough time can make an INFJ appear a lot like an INFP.
Even though I score INFJ, it's not clear to me what introverted intuition is.
S'ok!

I figured you weren't mad at me. It was just a bit confusing.
Well, I don't entirely trust online tests as some questions are vague or biased to make "NFs" so touchy-feely illogical or "NTs" so coldly rational they can't recognise their own pulse etc-- A good bet is in trying to see based on the tests (taken a few times, perhaps spread out), reading up on all of the Types to see which you feel best represents you (but be weary that some sites are either biased or have old, outdated info--) and try learning about Cognitive Processes to see which best matches yours. I like this
INTJ page on Cognitive Processes. You just pick the CPs from whichever Type at the bottom you feel is yours, and then compare it through the original descriptions for INTJs but just imagine it as INFP (or whatever) instead.
Also, both INFPs and INFJs need lots of time but for
different reasons. An INFP might not seem as outgoing or talkative as an INFJ. An INFP is not likely to interfere with people as they feel that people should have the freedom in learning from their own problems or sorting it out-- they do so with the best of intentions. The only exceptions is if they know the person well enough that they'll do it as they can "feel more confident and comfortable" telling them.
An INFJ is more likely to interfere with people as they feel that they should help the person in realising what they see as the problem and as the INFJ feels that they've already figured out what needs to be corrected, they're more likely to tell you what "you should do" to fix it.-- they do so with the best of intentions. An INFJ may tell just about anyone what they feel the person should do, but may hold back a bit with new people (or may not, if they feel comfortable or absolutely certian they should tell them.)
And an INFJ is not going to turn into an INFP any more than the reverse happening. If you feel that you are going into your
worst state of being resulting from severe/continual stresses, you'll likely look like a negative version of your Shadow Type. The Shadow Type of INFPs is ESTJs and for INFJs is ESTP.
Also, the Communication Styles of INFPs and INFJs are different. INFPs have an Informing style whereas INFJs have a Directing style.
As you've read, you must know that I've raved quite a few times about Vicky Jo's website on helping discern the differences of
INFJs and INFPs. Try it out and see which applies to you, if either.
------------------------
All INFP and INFJ depictions that I've made are going to be consistently updated in the
OP at the Bottom of the page until I feel my work is done. As well as my reponses to stereotypes mostly in regards against INFPs. :steam: and even unjustly praise for all INFJs (I know INFJs, it hurts to not think we're perfect or to let others know so but we aren't!

We're kinda close, okay?!

)
