How to overcome speech anxiety?
Studies have revealed that when giving increases, the amygdala’s activity decreases. The nerve that can calm the brawl response has been proven activated by acts of compassion and generosity toward others.
We feel boosted at ease and less worried if we are compassionate to others. Public speaking operates on the same tenet. We can combat the feeling of being attacked and begin to feel less anxious when we embrace speaking with generosity to overcome speech anxiety.

Keep your people in mind as you prepare.
We all make the error of beginning with the topic when preparing for a presentation. This quickly draws us into the specifics and makes it more challenging to tear down the barrier separating us from other people. Start with the audience instead.
Refocus your thoughts just before you speak.
Just before you talk, you have the most anxiety. Your brain tells you, “Everyone is judging me,” at this precise time. What if I mess up? You can redirect your mind at this specific time. Remind yourself that your audience needs your support. With your brain, be firm.
