Dr Lucy Hone is well-regarded as a resilience expert and she's got plenty of personal and academic experience with devastating grief.

Grief comes in many forms - not just with death, but divorce, estrangement, dementia, redundancy, and Hone's put her findings into a book.

She says some people are more 'mentally agile' than others and that learning how to balance emotions is a key skill.

"They're also typically good at being able to focus their attention on the things that they can change - and somehow accept the things that they can't. And I'm not going to pretend that that's easy or sugarcoat it, but all of my work is about helping people."
