I know it's not the best option but can't you cash them out in paypal (I don't know how are the regulations with paypal in Turkey), it's the easiest and quickest way? You loose a little bit but you can re-buy bitcoin again.
There is another option you can try but you have to have someone you can trust and someone who already have coinbase account. You can transfer coins between coinbase accounts while using only email address, so you can send it to this another person who can withdraw then you your other wallet.
There is a third option too, create a Coinbase Pro account and transfer the coins to it - it's free of charge, then try to withdraw from Coinbase Pro.

Those are the things I would try if I was in your situation.
