How do I re-formulate my research questions and restructure my thesis?

My thesis has become a nightmare that I am living, I cannot even concentrate on anything this thesis sucks all the time of my life. I just want to get done with it my guide keeps rejecting my thesis and I have become fed up with this whole process itself. I cannot understand what should I do to get my thesis approved? Since it is becoming humiliating to have to work on the same thing for so many years now. I am PhD student of Macro Economics, my research topic is smart services/ E-services provided by the government in Dubai. I need help in re-formulating my research questions and restructuring my thesis, these are the two issues that my guide keeps on emphasizing on time and again. It would be a great if any suggestion or proposition can be given that would actually help me come out of this jeopardy.
