I am a 20 year old boy. I am well in my studies. But now, I think my mind is diverting from my targets. I can't concentrate in my studies. I feel loneliness. My family is an atomic family. There are only 2 members including me. I am feeling lack of supports from others. I have only a few friends. My mind is asking the presence of a good friend. But it is impossible. How I can escape from this problem. How I can concentrate in my studies?
