Man, i know the feeling. I’m to present my research later this year for a couple hundred people and am nervous just by thinking about it. I’m not scared I’ll stutter though. I know that I will stutter, that is a definite. I’m more scared about how I will handle my stutter. Is it the stutter yourself or they way it will make you look that frightens you? Maybe talk to your professor. I guess he/she already knows about your stutter. Maybe he/she can help calm you down with some techniques he or she might have used as well. Everyone is scared of talking publicly, stutterers even more. I’m sure you will do just fine if you take it nice and slow and keep a focus on breathing. Good luck and please let us know how it goes!
