single love

   It must be the most sad thing in life ,the single love .

I am feeling very bad ,when I love the boy but he don't love me .God tell me what should i do ? I can't forget him ,and it is so difficult to delete him from my life.         

I want to start living another new life but my heart does not allow it .

God ,tell me ,what should I do ?   Please sent a angle help me . i  like dying in the sun ,just like the songs tell!
