To be honest with you, I cannot think of anything that worries me, only the fact that I might want to go to the toilet and I won't be able to!
It's certainly worse in a traffic jam!
It's like the thing that I dread most of all happens because I make it happen!
Weird, I've certainly never heard of anyone else that has the same sort of thing.
My husband knows exactly how I feel and now I can go almost anywhere with him in a car because I know he knows my fear!
I can travel on trains, but not the underground, on planes, on coaches (with a toilet), but not on buses.
As long as I have the security of a toilet I'm fine.
My husband used to have a small van, which I insisted that we went out in as in the back of the van I used to keep a bucket, plastic bags, toilet paper etc.
Sorry, I'm really sounding like some kind of weirdo... it's very embarrassing.
Thanks for listening.
