Explain Away

I should be happy but I'm not
I've got everything that I always thought
But deep inside I feel that something's gone
Explain away the shiver in my bones

For you, I've done all the achievements of a real grown up
But you forget, life is greater than you know
and I feel completely null

I should be thankfull but I'm not
I've got my wife, my house, my kids, a dog
But somehow I think of doing more
Explain away the emptiness in control
