Just before Christmas, a post on X garnered a lot of attention in the Irish quarters of the social media app. It was from Dr Cara Ghiglieri, a 34-year-old mother of twins from Belfast who simply stated “When my mum died of an illness I’d never heard of, I set myself a goal of becoming an expert in it. As of yesterday, I’ve officially achieved that goal. #PhDone.” The post was liked and shared tens of thousands of times, a stark reminder of loss during the festive season but also the power of determination and will.
