See above. I've heard there are two types of public speakers. Those who get nervous, and liars. I used to struggle connecting with people in general but I can shoot the shit with pretty much anyone now. In casual contexts.
You put in front of a group to do something as simple as reading a few prepared sentences though, I get a fight or flight adrenaline spike like I'm walking into an octagon. Let alone if I'm trying to pitch or explain some I personally worked on. I don't think I'm "scared" of it. I recognize that in these situations no one cares that much, most of the time. Yet the moment it's my turn to speak, I'm quiet, sound unsure no matter how well I know the topic, and have a deep voice so I'm hard to understand. I also shake like a leaf. I have a "familial tremor" that gets worse pretty much exclusively in these situations. Got any tips for sounding at least vaguely confident?
