Personally, how I survived presenting (in class or at work) is to actually not to practice or write a "script". I found that forcing myself to say certain words in a certain order triggers me more (much like when I'm asked my name, phone number etc etc). What I found that works, but not might be healthy, is to write down a series of points I want to cover. Important points or section of information that I can then weave into sentences, much like a conversation rather than reading. This helps me to be able to change words when I get blocked, or feel like I might. Not all stutters are the same, and not everyone is the same so this might not help you, but this has helped me. Currently at my job as a software developer we do daily stand-ups which is basically a mini-presentation every morning where we go around the room (zoom) and give updates on tasks. The only way I've been about to not stress over them every day is to just make a small bullet point list and try my best to flow them together. I found having the freedom to choose my next words instead of a script gives me the ability to make sentences that mean the same thing, but flow better. Another thing that has helped me, mostly in school, is that if your presentation is a slideshow (or something of that nature) is to point to things you are talking about. I found that even those few seconds where you can say "like this" while pointing at something, lets me catch my breath and know that everyone is looking at the screen rather than me. Like I said, this might not help you, but this has helped me greatly get through high school, college and my everyday. Not to mention, as i am sure someone will comment, this isn't the healthy way to deal with our stutter. I basically let it the fear win which enables it to be worse. However, better the devil you know... Either way, you can do this. Don't worry what others think, most of the time the kids in the room aren't even paying attention. As you get older (I'm 27yo) I don't even think about school or my presentations. Everyone I went to school with moved on with their lives, they won't remember nor care that one time you did a presentation and stutter. Be courageous, don't back down and take your time. Best of luck.
