Is the turkish translation right guys? Thanks in advance 

English

There I was, standing in the middle of the enormous Istanbul Ataturk Airport. At that very moment, I was the happiest human being on the face of the earth. I could almost fly from the joy, as my heart was about to explode inside my chest. At last, I was living my dream, I was in Istanbul, The City Of Dreams. 

Turkish

Oradadaydım, Istanbul Atatürk havaliman´in ortasinda ayakta duruyordum. Insanlarda en mutlu, oanda, bendir. Az daha sevinçten uçabilirdim ki kalbime göğüsümde patlamak üzere. En sonunda, hayalem yaşıyordum, Istanbuldaydim, Hayallerinin Şehir.

First sentence is right. At the rest of it, these are the right version of the sentences:

Yeryuzundeki en mutlu insan bendim. Kalbim gogus kafesimin icerisinde patlamak uzereyken, az daha sevincten ucabilirdim. En sonunda, hayalimi yasiyordum, Istanbul´daydim, Hayallerin Sehri.

Thank you very much, you have just saved my day
