Never mind.
I did some research on Fi.
It doesn't work for me.

BlueWing also makes a good point. The INFP will seem calm to others but is not calm him/herself, that's a part of Fi and I realize I can't relate to it at all.
From a cognitive function standpoint, forget any XXFP type!!
The reason why I was thinking about the switch is because I feel like that I'm a 'different person' in college than I am back home. The most important difference is while I have a good group of friends in both areas that I am a lot more quiet with my college friends than I am with my high school friends. It's weird I feel more like an E at home but more like an I at college (which I think may be simply due to the fact that I'm friends with more E's in college, now that I think of it..).
There are also different styles of dealing with each group (which makes me realize that I'm probably T over F).. back home, my friends and I (pretty much the Rational clique, also more ST>NF and 0 SF) have no problem saying whatever comes to our mind and making a lot of outrageous jokes. I can't really do that so much in college. I say mildly crazy things and they already think my jokes and witticisms are extreme, while my friends back home wouldn't bother to laugh because they would want me too try harder.. haha!
However, I would say that even though I'm not the loudest person in the group that I am energized by crowds. I enjoy parties and mingling with people.
One thing is that my friend is more knowledgeable about Keirsey (NT, NF, SP, SJ) than actual MBTI cognitive functions, so he wouldn't be able to explain Ni at this time.
He is focused more on observable behavior than anything else, he noticed that I tend to be more comfortable with one-on-one conversations than group conversations, so that was why he thinks I over E.
The F over T is more so because of the fact that I will often consider other people when making decisions and he believes that T types would actually have a hard time doing so and it doesn't come naturally. I think that T types with a well-developed F function (in my case: well-developed Fe) are very capable of high empathy and making decisions with that factor in mind.
I relate to the ENTP description more than the INFP one. I was more so taking into account what my friend thought about my type.
A reason why I doubt the Fi is that all the IXFPs I know are very touchy-feely and emotionally expressive once they are comfortable around others. I can't say I ever get that far unless I was fucking the person or something... then I wouldn't necessarily be emotionally expressive but touchy feely, yea, haha!
Also, I think my Enneagram type is 3w4- which to my knowledge is extraverted but very much a social chameleon.
So... ENTP.
