What to do when graduate admissions haven't gone well?
Do you want to go to industry or academia?

Turning down a scholarship to reserve the money for someone more "enthusiastic about it" sounds at odds with "my idea was to ... be academician [sic]". 

If you want to work in industry, unless it's for some deep part of, for example, Google or AT&amp;T, I would recommend getting a Master's wherever and begin getting real-world experience.

If you want to be an academic (and so almost absolutely need a PhD) then you should find people from Turkey who did something like what you are trying to do and get in contact with/ emulate them. 

At the risk of being provocative and with the caveat that I doubt this is the main issue, your message gives the sense that money is an issue. It is for many of us- but consider if you conveyed that in an unproductive way as you tried to get admissions to graduate school. Some in academia are touchy about that.
