Jessica, who was diagnosed with epilepsy in 2010, had bouts of amnesia following seizures before. But never like this. “My world fell apart that day,” she said. “I saw this woman running towards me I had no idea who she was. It was my mum – and I just stared at her blankly.” Her parents had to show her photos of the family together to convince her to so much as get into a car with them. Jessica looked in the mirror first to be sure it was her in the photos. “Sensing my fear, Mum put a reassuring hand on my knee, I shrugged her off,” she said. “The gesture felt too intimate from a stranger.”
