What about confronting crowd fear? I think I was scarred by my first presentation ever at the age of 12 (on DNA) in front of not 1 but 2 classes full of people, because I basically stuttered through the entire thing (speaking to 1 person- Fine. Speaking to 5 people- Fine. Speaking to 10 people- Mostly fine. Speaking to 30+ people- NOT FINE. lol). I took a public speaking class in college and they videotaped us while practicing and it was apparent that we improved but that was now years ago. I taught a couple small classes in things (or tried to) like SQL but they didn't fly very well. :/
The only way to really get over the fear is through regular exposure. Finding a local public speaking meetup or Toastmasters group is a great way to practice and build up your confidence.
