Being panic and exhausted during/after presentation. What to do ?

I am a PhD student. Recently, I’ve been feeling very nervous during Zoom meetings, especially group meetings or research presentations. When others ask me tough questions, or even something I can’t answer immediately, I start sweating. I feel like I’ve messed up the meeting, especially since English isn’t my first language. Even if the meeting goes well, I still feel exhausted and down afterward. This affects my productivity and causes more anxiety about upcoming meetings too. Do you have any advice on how to overcome this?
