When someone outside of our brains, outside of the people who have close personal relationships with us recognises us with ease, it bursts the complacent BDD bubble. It is a jarring back to reality that our bodies and faces don’t morph and change regularly, that we do look a certain way all the time. And there is a twinge of fear at the back of our minds because we don’t know what that certain look is. We don’t know what we look like, but this person does, and we will never know what they see, what strangers see. It is extremely depersonalising to be unable to comprehend how we are perceived by others. How do you recognise me when I can’t recognise myself? And how is it fair that you know my face better than I do?
