Existential depression is a depression that arises when an individual confronts certain basic issues of existence. Yalom 1980 describes four such issues or "ultimate concerns"–death, freedom, isolation and meaninglessness. Death is an inevitable occurrence. Freedom, in an existential sense, refers to the absence of external structure. That is, humans do not enter a world which is inherently structured. We must give the world a structure which we ourselves create. Isolation recognizes that no matter how close we become to another person, a gap always remains, and we are nonetheless alone. Meaninglessness stems from the first three. If we must die, if we construct our own world, and if each of us is ultimately alone, then what meaning does life have?Why should such existential concerns occur disproportionately among gifted persons? Partially, it is because substantial thought and reflection must occur to even consider such notions, rather than simply focusing on superficial day-to-day aspects of life. Other more specific characteristics of gifted children are important predisposers as well.

This makes complete sense, and in a very real way I think it’s what gives “ignorance is bliss” its power.
