Hi Beth,
I feel for you, it's a rough ride when you can't get past the barriers.
I agree that a safe person would be really good at this point, someone who understands just how strong the fear is. Even better, someone who has been through agoraphobia themselves. That way you might meet a new friend as well.
Maybe there's a link somewhere on this. If I lived near you I'd offer to come and help out myself!
Good thoughts to you, Myzen
