If you feel like you're going to cry can you excuse yourself and leave? You can let them know stuttering is a very sensitive and emotional subject for you. Most college people are pretty empathetic and honestly they'll probably be just as nervous as you because they're new SLP babies and don't know what they're doing. But sometimes simply having a sympathetic ear from someone is knows something struggles of stuttering can be helpful enough. I don't know how good the program at your university is though. But again, if you don't like it you can excuse yourself and leave anytime.
