In 1977, Ed Stewart was a happy-go-lucky teenager with his whole life ahead of him. With a new engineering job, a girlfriend and a motorbike, life was good. But when he dropped in on a friend’s party, a violent row with another teenager - who was carrying a shotgun - turned Ed’s whole life on its head.

Ed had to learn to navigate the world in an entirely different way, but he made a success of it - becoming a piano tuner to the stars and counting Jools Holland and Brian Ferry as his customers. Despite a life of adversity, he tells Dr Sian Williams how not just one, but two Life Changing moments led him to be what he refers to as a “glass-three-quarters-full” kind of bloke.

For Lisa Hover and her husband Andy, life on the Hampshire Dorset border with their family of four children seemed idyllic. Even when a routine sight test on their young daughter Annabelle picked up an abnormality, it all seemed manageable.

With no cure available, Annabelle was determined the most from her limited life span.

Lisa talks to Dr Sian Williams about the challenges, joys and sadness she experienced - and Annabelle's dream to have a white Christmas with all the family.

Sarah Fairbairns spent much of her life feeling she was a bit different. Growing up in the 1960s and 70s, she gained the reputation of a wild child – from travelling to India, to dancing on stage with the cast of iconic counter-culture musical Hair. And yet all the while, she faced bouts of sadness and depression, and a confusion as to why that should be. Later in life, Sarah made a discovery about a medical childhood trauma that changed the way she viewed the world – and wrote in to Life Changing to share her experience.

Now in her seventies, Sarah speaks to Dr Sian Williams about how confronting her past has provided belated but extraordinary relief.
