Glossophobia is the fear of public speaking.
in the words of Bryan Scudamore,
Despite the documented benefits, of public speaking, 74% of people are
terrified to get in front of an audience. But if you’ve
got a business to run and a story to tell, it’s time to
face that fear and embrace the power of public
speaking.

Its even worse for stamarrers like me... My project defense was a tug of war...had to struggle with communication all through but thank God it went well and I had a B in the end.
