Need Career Advice : Should I switch fields?

Hi all, I'm [23F] working in digital marketing for almost 3 years now, and overall, I’m okay with the work. The only part I really struggle with is client handling. I get anxious before and during client calls and because of that I sometimes feel like I don’t explain my thoughts well or come across as confident. Right now as a senior marketing associate I’m not on calls alone, my marketing manager or someone else is there to back me up. But as I move up the ladder, I know I’ll have to handle clients on my own and that’s been stressing me out. So, should I focus on improving my communication skills and try to get better at client handling? Or should I switch to a different field where client interaction isn’t such a big part of the job? If anyone’s been in a similar spot or has any advice, I’d love to hear your thoughts.
