How Can I?

How can I be happy
When I know that you move on
How can I smile
Now that you are gone

How can I look at other guys
When your running through my head
How can I sleep at night
When your not in my bed

How can I act normal
When I\'m trying not to cry
How can I move on
When you taught me love is a lie

How can I stop asking myself
What I could have done
How can I hurt so much
When my lifes just begun
