Loneliness doesn't just mean you don't have anyone. You have no relatives in the world. Rather, loneliness is where you have hundreds of loved ones and no one to understand you. There is no one who can open your mind and share everything you say. You spend the whole day laughing and joking with your own people and you feel helpless at night, it is also a kind of loneliness. This loneliness will only go away when you are emotionally full. There will be someone to understand you.
