Pursuit of Happiness

In this never ending world, with billions of people around, why many of them feel themselves so alone as the tiny Earth feels itself lonely in the infinite vastness of universe.

My thoughts are crowded with thoughts of those people, who want to care about me but cannot take care of me, want to be with me but cannot be with me, want to love me but cannot show their love. Some of those people are the most important for me in life and yet I am unable to do anything for them.
