Do you have Anxiety when it comes to Public Speaking?

I randomly have anxiety, it’s improved over the last couple of years but I notice it the most when multiple people are listening to me talk at once. My heart beats sooo fast and it’s like I can barely breathe but if I’m only talking to one person individually I don’t have any symptoms of anxiety unless it’s in a job interview or any other type of test, even if I know all the answers and I’m an expert in the subject. Having to speak and answer questions out loud feels like torture. Does this happen to anyone else?
