The presentation was split and I had only one slide. I prepared a text to read from and I was trying to prepare by only reading before the presentation and when I tried to explain by only remembering I had to read the text I had to hurry, but I was so nervous so I couldn't remember efficiently. I was in huge amount of stress for hours before the presenration, it is one of the most terrible things I experienced. I now realize that probably the reason is that I was much insecure about the things I talk and basically insecure about everything - about my performance and stuttering. The last presentation I had was better I probably stuttered only 3-4 times, but I prepared for it last night and I was rehearsing in front of my girlfriend.
