I look at my reflection time and time again, and I ask myself: "Is that me?" At some point during the past 3 years or so of my life (throughout which there has been no specific traumas I can name, recall, or otherwise), I have lost the ability to recognise my own reflection. Looking at recent photographs, I often have to take a few moments to recognise myself then. Older photographs are even harder to recognise, especially if I was unaware of the photo being taken. Do I suffer from some kind of neurological pattern-matching disorder? It reminds me of dissociative identity disorder, but I have no referential 'other identity(ies)' to work this from. Is this a common problem for 16-year-olds like myself, or am I going insane faster than I thought?
