Why do you cry?

I wake up in the morning,
i have tears in my eyes,
thinking about the day ahead,
and what it might bring,
i wish i could hold my head high,
but too many bad things have happened,
i haven't laughed that much lately,
cus i hear my mum crying,
why cant it go back 2 how it was,
when i wasn't born my parents were happier,
why am i here when i cause so much pain,
but i know,
i wont be happy again.....

*this is why i cry...*
