My dad passed away Nov 2020 and so much of what you wrote resonates with me. He was 70, packed a lot into his time, but still felt like he was way too young. So many diagnoses and illnesses. I’m so sorry for your loss.
I feel like if this was a. dad it would be reported as ‘a father murdered his children’. We need to make sure we are reporting accurately for both males and females when it comes to this sort of thing.
