I've had a couple of bad panic attacks in the past during my car trips to and from university with my mum driving. There wasn't really a particular reason, my mum is a good driver. Now I always choose to take the train to and from these places so I don't have to face being in a moving car on the motorway again. 

It's the sensation of the car suddenly moving fast, and the fact that you can't get out or ask the driver to turn over, that sends my anxiety reeling. Has anyone experienced something like this before and did you get over it?
