Mbti: Depression / Sadness for INFP

(Fi) Feeling Function: Own Internal values of likes or dislikes, importance gained through personal history. Usually only shown through action or "slip-of-the-tongue." - (Non-Verbal Function)
I really believe the (Se) Sensing function (the "Right Now" attention, focus and action in the environment) messes with them....
because they use the (Si) Sensing function. They are geared to keeping and desiring for things to stay the same. Naturally, the longer they do something, the more difficult it becomes to do something else.
(Te) Thinking Function: Is Verbal and External. They need to express their thinking and processes with others. (A togetherness sense of view)
(Ne) Intuition Function: helps them to stay open to New and Different mental information to discover, explore or expose. Because it is a Consistent curiosity and sense of wonder.
