You're definitely not alone Kristy!
I really would like to visit London again as have not been there since the meno symptoms became too much of a problem...but I saw images of it on tv last night and the manic rushing of traffic and people really put me off!! I think I'd have to take a valium to be able to cope....
Shopping malls make my head feel really weird too but I don't have to go in them very often but when I do, I try to make sure I'm not tired (which always makes my anxiety worse).
The difference now is that I may get a wave of anxiety come over me but generally I know how to deal with it whilst it passes (though not always!).
Try to keep eating out etc as this will retrain your mind that there is nothing to be scared of....good luck x
