You can hold yourself back from the sufferings of the world, that is something you are free to do and it accords with your nature, but perhaps this very holding back is the one suffering you could avoid.
Some authors have conceptualized depression as a "depletion syndrome" because of the prominence of fatigability; they postulate that the patient exhausts his available energy during the period prior to the onset of the depression and that the depressed state represents a kind of hibernation, during which the patient gradually builds up a new story of energy.

There exists, at the bottom of all abasement and misfortune, a last extreme which rebels and joins battle with the forces of law and respectability in a desperate struggle, waged partly by cunning and partly by violence, at once sick and ferocious, in which it attacks the prevailing social order with the pin-pricks of vice and the hammer-blows of crime.
I am now the most miserable man living. If what I feel equally distributed to the whole human family, there would not be one cheerful face on the earth.

Imagine a society that subjects people to conditions that make them terribly unhappy, then gives them the drugs to take away their unhappiness. Science fiction? It is already happening to some extent in our own society... Instead of removing the conditions that make people depressed, modern society gives them antidepressant drugs. In effect, antidepressants are a means of modifying an individual's internal state in such a way as to enable him to tolerate social conditions that he would otherwise find intolerable.
