Smile through the tears

Smile like nothings wrong,
smile like life's fine,
smile through tears of darkness,
smile through those tears of pain,
smile through all the i hate you's,
smile through all the i don't care about you's,
smile like you mean it,
smile as thoguh this nightmare isn't real,
smile like you just don't care,
smile through the tears,
smile for the purpose of being alive.
