Just go through with it. Stuttering isn't a disease or smh. It's a part of your identity that makes you different from the rest. The sooner you make peace with stuttering, the sooner you can move on with your life. You will begin to notice things in life differently. You will gain a new confidence. Last year, my group (5 members) were given to do a presentation. I made the presentation and divided the work between the members. I didn't want to speak at first. I was afraid that people will hate me. I had even begun to hate myself. But when I got into that stage and faced my classmates, I forgot about my stuttering. I gave the presentation stuttering with every single word at first. My friends didn't seem to care about my stuttering. They were listening the whole time. I suppose all of them already knew back then. That was a defining moment on my life. I began to notice what I've been missing out: debates and mostly asking questions. I did volunteering after that (stuttered while asking people for money to donate). My advise is to just go with the task. It's not a big deal that you stutter. Believe me, your class already know about it. Stuttering is a part of our identity. Don't let it push you back. It's gonna be okay I promise. Sorry for my long story. :)
