also, everyone's ideals are unique, but i think well-developed intuition enhances this greatly. it makes everything about the big picture (ie Ni). you want to fix the entire world. and you have the experiences in your crawl that help shape and define what that imagined Ni world looks like.
nothing wrong with being unique. a lot of people on this board seem to resonate with what you say, me included.
as to the op-
i don't really feel like this bc i've always been really dependent and wary of social commitments. however, the more extraverted and social i become, the more i feel myself slipping down this tunnel. i think a related corollary to this is that N people generally seem to appreciate what i can do far more than S. and, as a result, give me back more in immediately usable currency.
i also think part of the problem is that there are just a lot of people like this, floundering, struggling to get by, scrapping for every last bit they can get off of anyone else. being an Fe just makes it so that you are more likely to notice where they are coming from and wanting to lend a hand hoping you can make a difference, turn the tide, etc. but you're also more aware of their under-appreciation than other times, when they are not showing any authentic gratitude as a result or capable of returning what you do for them.
Fe with Ni needs to get away and develop its own reservoir, support structure, technique to stay afloat, etc. it is far less grounded and practical and sure of itself than sfj Fe types. it can only rely on external support so much, the information it needs to work with to help manage Fe moods and frustrated ideals needs to be in play in the introverted intuitive environment. NT friends are probably helpful with this as well, as are other NFs (always).
