Sad?

Don't know why suddenly feel sad..
But nothing happen..
I think because of I listening song...
Everytime I'm listening balad song i will feel sad without any reason..
Today I sad because I go to school?
I will meet him at school?
I want talk with him but I feel scare..
I thought that I'm brave but now I know that I'm cowardly...
I really hope got 1day he will talk with me again..
