You can feel lonely in even the largest of crowds. Loneliness only exists if you have lost all that is valuable within you and have been left like an empty shell. In even the loneliest of places, your soul can feel joy. Do not seek others to keep you company; do not expect others to keep your sorrow at bay. Find out and see what makes you happy, and fill yourself up with it. Fill up your shell, and the loneliness will disappear. Then you will be ready to go on; you will be happy regardless of how many other people are around you.
