Why arent you?

Since you told me,
i have been numb.
theres a hole in my heart,
that just wont heal.
A hunger in my soul,
that food cant fill.
you say u still love me,
then how can u do this?
i look at you and cry
i see you laughing and making jokes,
i know your eating and going out
passing your time as if nothing happened.
Why aren't u hurt like i am?
why aren't u depressed like i am?
Why does your sun still rise,
when mines been frozen?
why does your heart beat,
when mines been ripped out?
