For a few years now I've suspected I've had this. I can leave my house with no anxiety, but when I go out of town I have a lot of anxiety, panic attacks, feelings of being disconnected from the world, and difficulty with swallowing food. It seems to be worse when I'm in the car, like when someone else is driving and we're traveling outside of town. I also appear to be more anxious during the day than at night. I don't know, but does this sound like Agoraphobia to you?
