sad sonnet

It's useless to love you
I've known this from the start
I am not one who can disapprove
Nor can I stand for us to be apart
I look up to you like a little pup
But we're so different I feel like to hide behind a veil
When my heart is down, yours is up
When you are sad, I try to cheer you and fail
Sometimes my hope does swell
Then you turn cold and I feel I should depart
I am no god, I am no angel
I'm simply a girl with a broken heart
My love for you will never die
But one day, sweetheart, my tears will never dry.
