Missing

Someone is missing:

Age - The same as mine

Height - Varies

Sex- None

Weight- None 

Distinguishing features - Changes shape and size

Last Seen - A long time ago

He (for lack of a better term) has been my
companion throughout my life. In good times
and bad, he has been by my side. I know he is
very afraid of the dark. And overcast days.
And being inside.

At the moment, I stay mostly in my apartment.

And when I do venture out, well I can't remember
the last time I saw blue sky when I cast
 my gaze upward. And never a sign of him.

My friend has disappeared. Maybe he has forgotten
who I am. Maybe he is wandering the streets
right now trying to find me. Maybe scared
and alone. I am very worried. I miss him terribly.

His name -  Oh, I am so sorry, that should have
been the first thing I told you.

He is known as "My shadow."

PS - Look who I found today!!
