"We often pity the poor, because they have no leisure to mour..." — Anne Brontë quote meaning

We often pity the poor, because they have no leisure to mourn their departed relatives, and necessity obliges them to labor through their severest afflictions: but is not active employment the best remedy for overwhelming sorrow--the surest antidote for despair? It may be a rough comforter: it may seem hard to be harassed with the cares of life when we have no relish for its enjoyments; to be goaded to labor when the heart is ready to break, and the vexed spirit implores for rest only to weep in silence: but is not labor better than the rest we covet? and are not those petty, tormenting cares less hurtful than a continual brooding over the great affliction that oppresses us? Besides, we cannot have cares, and anxieties, and toil, without hope--if it be but the hope of fulfilling our joyless task, accomplishing some needful project, or escaping some further annoyance.
