Why is loving somebody so sad？ Lately i am a little upset.just can not concentrate on anything. Once i saw some beautiful words. "I need 3 things in my life. The sun for the day. The moon for the night. And you forever." i still have not met "you". There were some persons who liked me,but i just can not find my person. I know i have a lot .My parents love me,my friends love me .But i sometimes feel like i have nothing and being so lonely. Is there anyone who ever feel like that way?
