“Toska - noun /ˈtō-skə/ - Russian word roughly translated as sadness, melancholia, lugubriousness.

"No single word in English renders all the shades of toska. At its deepest and most painful, it is a sensation of great spiritual anguish, often without any specific cause. At less morbid levels it is a dull ache of the soul, a longing with nothing to long for, a sick pining, a vague restlessness, mental throes, yearning. In particular cases it may be the desire for somebody of something specific, nostalgia, love-sickness. At the lowest level it grades into ennui, boredom.”
― Vladimir Nabokov

“All great and precious things are lonely.”
― John Steinbeck, East of Eden

“Man, when you lose your laugh you lose your footing.”
― Ken Kesey, One Flew Over the Cuckoo's Nest

“Catherine Earnshaw, may you not rest as long as I am living. You said I killed you--haunt me then. The murdered do haunt their murderers. I believe--I know that ghosts have wandered the earth. Be with me always--take any form--drive me mad. Only do not leave me in this abyss, where I cannot find you! Oh, God! It is unutterable! I cannot live without my life! I cannot live without my soul!”
― Emily Brontë, Wuthering Heights
