Can you speak in front of large groups?

Title for reference. So today at uni we had our first tutorials for the semester. I can't talk to groups of people all that well, and so was really nervous. Like, I could feel my body temperature rising every second I was in front of everyone. Anyway, I'm reading a text for everyone and half way through the paragraph I see: [Quote]Their social inden- [b]tities[/b]... [/quote] And then I just burst out laughing because it looks like the word "titties". It's not even funny! And it wasn't even a short chuckle, I'm talking about a nervous fuelled laughing fit where I just couldn't hold it in. So god damn embarrassing.
