Public speaking is one of the most frequent fears.
There is an organization with a local club that will welcome you and help you. It is called Toastmasters.
Best of all it is inexpensive and fun!
I was a Toastmaster for a number of years. I would still be a member today if not for my hearing getting so bad that I can't participate.
Toastmasters is a communication and leadership organization. Everyone joins to improve their communication skills and then find out that their leadership skills also benefit.
The clubs offer you a chance to speak and be evaluated by your peers in a non-threatening environment. You will quickly learn to discard those annoying filler ah's, um's, you know's and dude's when you speak. (Most charge you a nickle every time you utter one in a meeting — luckily for me, my club had a quarter maximum fine.)
I joined, got my info packet and soon gave my first speech at the club. Not very much later, I was recruited as an officer. I volunteered to write a weekly newsletter. I progressed.
In due course, I completed enough speeches and leadership positions to earn my Distinguished Toastmaster award. The DTM is the highest award available. I won several state level newsletter competitions and won two International newsletter awards. In 1985, I was named Toastmaster of the Year for District 47, out of the 3,000+ Toastmasters in Florida and the Bahamas.
Toastmasters gave me the confidence to give presentations at technical conferences across the U.S., give keynote speeches to statewide conventions, speak on the rubber-chicken circuit in my community and give seminars for my company's HR department. All this, despite the fact that I am an introvert supreme.
At one time, I got my boss involved with Toastmasters. One day, he gave a speech on our company's promotion procedure. The example he showed on the overhead projector was my promotion package. What a pleasant surprise. My work with HR and my speaking gigs at conferences was heavily noted in the packinge. In 50 years of working that is the only title promotion I ever received.
I have seen so many success stories among my Toastmaster buddies. I hope you will investigate Toastmasters and will share your success story with me. Peruse their website and find a club near you.
