"Many people think of loneliness as isolation, but the difference between these two terms is substantial. Loneliness is the subjective feeling that you're lacking the social connections you need. It can feel like being stranded, abandoned, or cut-off from the people with whom you belong - even if you're surrounded by other people. What's missing when you're lonely is the feeling of closeness, trust, and the affection of genuine friends, loved ones, and community."
