Standups are supposed to be uncomfortable for everyone which is where they got their name: they are supposed to be 5-10 minute tops run throughs where everyone is standing to remind them to not get too comfortable or talk too long.

The problem may not be entirely you: 30 minutes each sounds like at least some some of your coworkers in those meetings are far too "comfortable" and taking too much time giving too many details that don't matter to what the standup is supposed to get across. (It's not supposed to be a list of all the work you've done, but to find places where you can cross-cut: work you did that may help someone else but neither of you realize it; problems you have that maybe someone else solved earlier.)

The other indication that there may be process breakdowns around you outside of what standup is supposed to mean is that standups were originally supposed to be only engineering (in theory). A "product standup" with directors, executives, and managers doesn't sound at all like what a standup is supposed to be, to me, it sounds like a daily micro-management checkin meeting.

You probably don't have any power to fix a broken process, but if it gives you some small comfort, it may not be entirely just you in this case. Your meetings may be asking more of you than they are supposed to be and of course that adds additional anxiety and stress.
