Whenever I sit in a work meeting on Zoom (they are all still online, we are all working from home for the time being) I feel alright if I can sit silently, if I have to speak my heart rate goes absolutely bonkers at the mere thought of it.

But I've realised the really difficult part is after each meeting. Even if I haven't spoken at all, when the meeting ends I get hit by a wave of panic. I then struggle to get any work done for the whole rest of the day. I'm feeling anxious and panicky with a tightness in my chest and nausea. My mind goes foggy and it's really hard to concentrate. This lasts for hours and hours despite my attempts to calm down (breathing, meditating, calm music, walking, etc). On days with no meetings I get so much more done because I feel calm.

This happens when there's no prospect of me even saying anything in the meeting! And hits me when the meeting is over.

What can I do? My productivity is really suffering.

I've been to therapy for several years with a wonderful therapist so please don't suggest therapy as I'm on that already. Thanks :)
