I get panicky before every meeting even small ones

It's not even big presentations — a casual team check-in sends my heart racing. I rehearse what I'll say, worry I'll be asked something I can't answer, and spend the hour before feeling sick. Afterwards I'm fine, sometimes even fine during, but the anticipation wrecks me every time. My manager thinks I'm confident because I speak up. Nobody knows I was shaking under the table. Does anyone else dread meetings way more than the meeting itself?
