My mum died when I was 20, 7 weeks after her 52nd birthday. When she first died, and in the years afterwards, there have been so many "firsts" and big events without her, graduating, my first job, getting married, having my children and when I turned 40 knowing I'd been without her for longer than I'd had her in my life but I feel like this day has loomed over me forover 30 years and now it's here I don't quite know how to feel.
