A very complicated F1 visa administrative processing issue... What are my chances if I reapply? Greetings from Turkey,

I got a fully funded PhD offer from Illinois Institute of Technology on last April. I applied for an F1 visa to enroll in for Fall 2016 semester. Even though I got an approval on my interview, my application status remained under administrative processing for almost six months. I had to defer my admission twice, regardless of my efforts and the university's efforts to contact the embassy several times, since they were extremely indifferent and unhelpful. At the end I got really upset and sent the embassy a veeeeery long e-mail that contained literal sentences like "I can't take this anymore", "WHAT COULD I HAVE EVER DONE TO DESERVE THIS?" and "Even if I get cancer and the only cure is in the US, I will never set foot in your country" (I wasn't drunk or high). At the end of the e-mail I requested the withdrawal of my application, which they instantly agreed to like they had been waiting for me to give up already.

My supervisor is trying very hard to help me and he is the coolest person on earth. So, I don't want to let this chance slip away. My question is, what would happen if I tried to apply at the same embassy. %100 administrative processing again? refusal for life? Should I apply for this visa at a different country with a valid excuse (I might do an internship abroad). Any suggestion will be highly appreciated. Thanks in advance.
Visa questions are best asked in expatriates.se but here's an abbreviated answer. 

Visa application voluntary withdrawals are normally without prejudice towards future applications, however you showed a great deal of emotional immaturity in writing the letter the way you did.  This might have been noted in your file. 

The only way you can know is to try again. Note that trying to game the system by applying from another country may actually result in greater scrutiny of your file than if you simply reapplied from your home country. 

Returning to questions of academia. If I was your future advisor, I would certainly consider this a negative indication of your maturity and readiness to engage in a PhD program.
