My attempt.   Its melancholy.  Its something like. (I am sure about the mood, translation may be is imperfect)

"Istanbul are you alive for me or dead.

If saying what is alive with you.

Passion alienation (loneliness)?

Vague feelings inside writhe about.

Your pain in my back doesn´t quit.

From empty and lonely streets for my part

To long for or be longed for is also empty.

From now on I am empty for my part."

My try,

 İstanbul

Are you life to me ,death ?

İf you say,what he has been lived with ?

Love ? speration?

The indefinite emotions i suffered

İt hasnt left my bitter back

You consist of empty and lonly streets İf i long to too,if im longed too, empty....

Then,your alltogether empty for me

But im a bit very confysed by this part !

İstanbul..

Are you life for me, or death?

Tell me, what was it I experienced with you

Was it love or separation?

For me you consist of

The confused feelings that a wrestled with

The pain you caused that never quit following me, and

Empty and lonely streets.

It is pointless for me to miss you, or to be missed

Now you hold nothing for me...

A heartfelt "thank you" to Longinotti, Canli and especially Marion for all your efforts.
