Hi Strongernow. For what it's worth, I think that dissociating, or becoming otherwise highly anxious and/or distressed, in the context of shopping centres or malls, is really really common. I certainly never thought so and naively assumed it was some strange little personal torture, but recently there was an entire session at my trauma therapy programme dedicated to the issue of shopping stress (and public places more broadly), and I was absolutely amazed to discover that almost everyone has huge difficulties with this task.
I know that for me, grocery shopping is a routine nightmare that is often intolerable. Shopping for clothes, er, doesn't happen. It just doesn't. All the usual shopping horrors, plus a whole load of extra issues dealing with body image, personal appearance and other markers of overwhelming self consciousness and shame.
While we all, obviously, have very different triggers, I think there is an above average likelihood that we will find at least one of them in a shopping mall, as they are such dynamic, sensory-rich, spontaneous, random, unpredictable environments in which seemingly a hundred thousand people are doing a hundred thousand things that involve a hundred thousand behaviours and activities. Just the sensory intensity of a shopping centre is enough to push my anxiety meter into overdrive.
I'm so glad that your hubby was there to offer at least some degree of anchor for you. I'm sorry that I don't have it in me to offer anything much more other than to say... I empathise, really really deeply.
