Hey man, I am Viktor 19M from Bulgaria. I also dreaded presentations 3 years ago, but now I regularly give them to help people also conquer stuttering like I did. I made a detailed post on what I did, which you can see [here](https://www.reddit.com/r/Stutter/comments/1iej02e/how_i_conquered_my_stutter_got_jacked_at_the_same/). In simple terms you have to practice. A LOT. Practice so much that you get confident presenting in your room, completely alone. Then do some breathing exercises before your turn to present and go for it. Track your progress (Your successes and losses). I promise one day, you will have that first successful presentation and feel OVER THE MOON ELATED. The next success will come easier after that. That is what I did in a nutshell, to defeat my fear of public speaking. Anyone can freely reach out and DM me or catch me in one of the Stuttering Support Group voice calls, where I give stuttering improvement advice. Have a nice day!
