Thanks for the help guys

Yeah pretty much the moment I stopped speaking the panic ended and I just felt embarrassed, but the moment I started speaking again it's like I couldn't even speak and I had no control over myself or my voice or my body, and looking up and seeing people looking at me with these kind of concerned looks made it worse. No one said anything but they definitely noticed. They probably just thought I was someone who hated public speaking and wanted to cry as opposed to all the crazy stuff that was going on inside my mind and body.
The mark wasn't that important so I don't think it was that :/
It just sucked going home after and crying and feeling so stupid, but I have another presentation next tuesday and I guess we'll see how that goes, hopefully this was a one off!
