I think that being alone and loneliness is two different things. One can be alone without feeling loneliness, the same way, one can feel loneliness while being surrounded by people [other people mentioned the quality and health of relationships]. When one feels that the Sisyphean task is easier because other people go trough it is comforting. But I think what would make this experience easier is, being aware that it is more absurd to end it. One may put oneself in the crowd to feel the warmth, or one can worm one’s mind and stand for what one believes.
