Public discussion for completing my degree.

Public discussion for completing my degree. Hi guys, I'm an italian girl and in Italian university in almost all universities, to graduate you have to speak in front of the commission about a work you have done (thesis). What can I Say, except I'm not sleeping because of this and I have my discussion in two weeks. I don't normally stutter , in fact when I vented about this with my family, Friends and boyfriend they were all confused because they thought I didn't stutter anymore. I even talked with the professor supervising my thesis, buy even him didn't take It seriously because I never stuttered with him or during his exams. During all my three years of my degree, I Always managed to be the last one in my oral exam so I didn't have much problems expect in 1/2 occasions when I was pretty stressed and stuttered a lot. So for explaining my situation nobody except some professor knows I stutter because I Hide It pretty well o didn't stutter at all when I am relaxed. Now the real problem, All I can think about every single minute of the day since I passed my last exam and known that in 2 weeks I have to do this , Is my shit public speaking , and I know I Will stutter and I cry only thinking about it, I am sick to my stomach every day thinking that I won't even make a single Word come out of my mouth, and I pictured that Moment every single minute. Luckily this speech Is not in front a lot of people, Is in front of the committe ( 7-8 professors) and the people you decide to invite, wich in my case will be none. I feel bad also for this because everyone will think I am weird because everybody invite Friends, family ecc. So for this ti Say, anyone has some advice?
