Badfish, i totally understand. after my nervous breakdown and the agoraphobia that came with it, my awesome mum would take me to a little shopping centre, then a slightly bigger one with more people, until she had me at a huge mall, quite unfazed by it. but its still a huge problem for me. i have plans in the city on saturday night, going right into Sydney for a festive girls night out, and i am already SO anxious, the city always makes me anxious- no room to move, breathe, so many people etc (i live an hr outside of sydney in a rural district with wide open spaces!) so this is tough for me and i totally understand how you feel.
you are not alone in feeling this way, i bet there are hundreds of other AP sufferers who feel the same- i know i do! keep your chin up and be strong, and know that i respect your journey.
