From Wikipedia:  Glossophobia or speech anxiety is the fear of public speaking.^[1] The word glossophobia derives from the Greek γλῶσσα glōssa, meaning tongue, and φόβος phobos, fear or dread. Some people have this specific phobia, while others may also have broader social phobia or social anxiety disorder.

Stage fright may be a symptom of glossophobia.^[1]

^{Ever since I started coming here in 2012, by coincidence a local friend recommended me as a guest speaker on PTSD and churches have been asking me to share, while respecting the anonymity of my peers here, about what we learn here in PTSD recovery.  I've been really luck to have had a 6 year streak without a really negative experience.}

^{Until today.  When I pulled into the church parking lot today, for the first time in 6 years the church didn't have me advertized on their sign, which was odd.  When I walked in, nobody greeted me as they usually do.  When I picked up the church bulletin, I saw they had changed my talk's title without telling me.  As I spoke, you could have heard crickets chirping.  When I gave the same talk at another church two weeks ago, folks laughed at my jokes.  Today not a chuckle.  At the end two weeks ago I got applause.  Nothing exceptional, just the polite applause folks give.  Today I got yawns.}

^{Afterward during coffee hour nobody came up to shake my hand or sit near me.  Finally, I just took my dirty coffee cup to the kitchen and left.  Nobody seemed to notice.}

^{I get why people have glossophobia now.  It was a really unnerving experience.}

^{I teach at a community college, and I'm having a little stage fright tonight just thinking of getting up in front of my class in the morning.  This glossophobia is real anxiety stuff.}
