Every month, my explosive rage would send shockwaves through my family. Then I got a diagnosis that changed everything

Laura Daly was six the first time she suspected something was wrong with her mum, Wendy. Furious at locking herself out of the house, Wendy reversed and rammed the car into their garage door once, twice, then three times, as Laura sat silently in the back. Eventually, the garage door contorted just enough for Laura to squeeze under, get into the house and fetch the keys.

“It was like I was watching myself,” Wendy Barker, 56, says of this moment now. “Nothing would’ve stopped me.”
