At this very moment I am shaking with a pretty elevated anxious state.

In two hours I board a bus for a 3 hour trip. The weather and roads are terrible. I am afraid the bus will go off the road. It is the busiest day of travel (in Canada) of the year. I am not looking forward to the crowds - and to be stuck on a bus with people who will be in my way if I need to escape. To an extent I am also worried about being judged by all these people. I also have a fear in crowds of other people's own behaviour - crying missbehaving kids, people playing music too loud, someone being irritating, etc. I suppose what all this comes down to is a fear of lack of control.
