You are talking about it. That's a good first step. As a PWS, I can say that people don't really care how you speak. It's only YOU who is stressed. I have started disclosing people about my stutter and it helps me to stutter freely without the awkward look on their face. I am a college student too, don't miss classes. Let your professors know about stutter, they are okay with accommodating presentations for you. I gave 2 presentations last semester and disclosed stutter before, it's not that hard. Good luck!!!!
