I was am a coward

I like a people. There's this person I like. Love at first sight. When I first saw he him when I was very excited. At that time, I think I was destined to like this people person. I know knew he doesn't wouldn't like me, so I just wanted to quietly looked look at him happy. and If he is happy, I will be happy.
 I hope I can see him every day. In School Road, in the cafeteria, in a variety of activities; I want to know the news of him what's going on with him every day. I'm always searching for him in the crowd. I am so eager to see him but this makes me very upset because I lost myself. I began to worry about me whether I am beautiful enough, I began to care about other people's evaluation what other people think of me and, I began to want to let oneself become better improve myself. But I still can't together be with him, because I know he doesn't like me. I silently watching watch him in the back from behind. I hope he can live well, I hope he can does not feel lonely, I hope he can find me in the crowd watching him, and I hope he knows I like him. 
In spite of how I hope strong my hope is, but I can still only secretly like him, because I am a coward.

Sounds like you're very upset about this boy. I know it's very hard to believe, but you will get better at talking to other people as you get older. Maybe you will never talk to this boy, but I would bet that one day you will talk to a very nice boy/man and get to know them very well. Good luck!
