I definitely understand this. I'm in my clinical years and I have to do case presentations every three weeks. At first I was so nervous that I thought what if I just go talk to the professor, maybe to work something out. I explained that the hardest part is the introduction(for some reason my name is a huge block). She agreed to let me use a nickname, and if I got stuck, she would do the introduction for me(as a temporary measure) Yeah so maybe ask, you might end up having a good deal
