Public Speaking

Does anyone else’s body and mind react as if they’re being held at gunpoint evey time you have to public speak ? I have a job where I do a lot of outreach. I have no trouble speaking with others one-on-one, even small groups. But when it comes to team meetings where I have to speak I’m a mess. I do a lot of hosting and presentations and I have to public speak. I tend to rush and speed up to get it over with, my voice starts to shake, and I avoid eye contact by looking at the board. I have my tools but they don’t work, practicing hasn’t worked, acting like I don’t care hasn’t worked. Breathing exercises, grounding exercises.. and nothing. I’m constantly exposed to it now and kinda hate it, but love my job. I’m wondering if anyone has any tools or tricks that has helped them to overcome or get more comfortable public speaking ? As I have a presentation tomorrow morning 😀
