I copied this quote. "INFJs can struggle with depression. This may stem from feeling chronically unheard, useless, or misunderstood, as well as from dissatisfaction with the
INFJ’s careers or the
INFJ’s relationships. Because Ni perceives the world so differently and profoundly, INFJs often experience a sense of loneliness and isolation, even when they are with other people. Depression may also arise from feeling that their ideals and insights are not being recognized or actualized in the world. They may see the world as deaf to, or unconcerned with, the truths they espouse. INFJs may therefore question their value in a world that seems indifferent to their insights". This is how I perceive them. How does this compare to your concept of "temporary fragility"?
