In August of 2006, Teresa Clark was driving five of her friends back home after a day at a music festival. Several hours into the journey she fell asleep at the wheel of their people carrier and crashed. Three passengers were killed, two others were injured as well as Teresa herself.
She was convicted of causing death by dangerous driving and spent time in prison. The guilt and shame of carrying that loss of life almost destroyed her. But in the 17 years since it happened Teresa has rebuilt; she now works in the mental health and wellbeing sector trying to keep the vow she made to live her life for her friends, and do some good in their memory.
She tells Dr Sian Williams how she has rebuilt her life in the years since - keeping the vow she made to live her life for her friends, and do some good in their memory.
