Nervous about CAC public transit.?

-I have to take government funded mini bus transit to my doctors appointments from now on and I'm really nervous. They'll be here in 30 minutes or so. What could calm me down? (I've already taken Xanax). I just need some words of wisdom.You will be fine.....We all go thru times like these!What is there to be nervous about? People ride the buses every day.
