Paranoid Meeting Symptoms

I'm worried about the meeting, but it hasn't even started yet!

I'm thinking about all the things that could go wrong, and they're all going wrong, aren't they?!

Should I make a quick exit or stay and try to reason with the meeting attendees?

I'm just going to pretend I didn't receive that email, and hope it goes away...

I'm doomed, I just know it. The meeting will be a disaster, and I'll never recover...
