I had to take a public speaking class just last year, and during my first presentation I picked the number 1, so I had to present first. I started off okay, but then lost my confidence and my voice started shaking and I found that I couldn't even speak, so I just kind of went like "yeah..." and ended my presentation early, grabbed my USB thing from the computer and went ot sit down as I started crying. Basically once I got to my seat I started sobbing and yeah, it was absolutely horrible! VERY embarrassing. I mean, everyone was nice about it and stuff, but still I was just like "oh gosh, they all think I'm such a weirdo now!"
Another time that year, I was in a different class with the same people and i had to make a presentation, and I started crying right before I had to go up to present. I was like hyperventalating and shit. Again, everyone was nice and the teacher was nice and said that I could just present next class. When I finally presented the next class I did alright and managed to get through it just with a red face and a shaky voice.
Such embarrassing moments! I hated that stupid fucking public speaking class.
