You are...

 The morning rises alone,

but the night falls with you...

An empty shell, is all I am,

you are the middle, the taste I crave.

My abandoned heart,

found in your arms...

Sightless eyes,

focused on you....

I fall apart,

you put me back together..

I am the mess,

you clean up,  unlike a bed of nails,

you are my comfort, my sleep.

I am the dark clouds,

you are the sun, that chases the clouds away...

I am the desert,

and you,

you are my oasis...
