Where'd You Go?

Where'd you go?
You've disappeared, it seems
Into thin air.
Where am I?
You're not here to guide me,
To show me who I want to be.
When you were here,
My life was good,
My path was so clear.
But since you left,
I can't see a thing.
I need you back,
I want you here with me
to shield me from the cruel world.
Please tell me when you're coming.
Where'd you go?
