I suffer from panic attacks which stemed from driving on the motorway and eventually ended in me being petrified of pretty much any form of travel. My worst are trains and being in a car on the motorway (still!).
I always get the feeling of being "trapped" as you can't get off a train inbetween stations and even if I did get off, I would be in the middle of nowhere, far from home. Its the same with motorways. If I don't like it, I have to wait till the next exit to get off. You can't turn round or anything. The thought of being in a traffic jam on the maotorway is my worst nightmare.
Does anyone have the same fears?
