Hi,
1) I can walk alone almost anywhere. However, I would really struggle to walk over a brigde or in a tunnel.
2) Again with someone almost anywhere, but would find a bridge difficult.
3) I can drive alone within about a 15mile radius. However, I still get mild anxiety when I venture out of a 5mile radius, but I do do it. I could never drive on a motorway on my own, or any real distance away from home.
4) Again, it's okay within a 15mile radius when someone else is driving. I still could never drive on a motorway with someone else in the car. Even if someone else is driving, hubby included, I still struggle to go on a motorway. I have done it when absolutely necessary, like going on holiday, but it's really difficult. If it was someone I hardly knew, I would not be able to go on the motorway.
