Long I have been afraid of my feelings. Specially Fi, but it's a useful function. It is philosophical and deals with getting yourself purified from your sins, a way to inner peace with yourself and the world, undestanding where you come from, nurturing and connecting deeply with other people and the world. Fi is a result of psychotherapy, becoming in contact with your complexes, discovering your feelings, understanding how relationships work. At least I understand it so. Can others explain more about this? I wish to make it stronger to get better relationships with others. Feel welcome to share your knowledge.
