The co-founder of a pioneering mental health charity has put a call out on social media to help her find the stranger who saved her in one of her darkest moments.
Jazz Thornton, the global mental health advocate, TV director, author and co-founder of Voices of Hope, posted on Twitter that she'd unsuccessfully tried to find the man by other means.
"Twitter, I need your help to find the man who saved my life: A thread," she began.
"In 2015 I attempted to take my life multiple times. One of those times, I went into a forest and began the process. I didn't tell anyone where I was or what I was doing as I was determined for it to work."
But as she slipped into unconsciousness, a man and his son, by chance, found her and called an ambulance.
"I ended up in a coma. When I woke up the doctors said that any longer and I would not have survived," she wrote.
Due to legal precautions, she was unable to name the exact location, but it was in the area of St Lukes on June 6, 2015, she wrote.
"I want to thank this man but I don't know who he is.
"I want him to know that I not only survived, but I fought and now help others for a living. He is a real life hero."
Thornton's remarkable story is told in her first book, Stop surviving, start fighting, which was published in March.
In May this year the mental health advocate returned to the spot where she'd tried to take her life five years earlier.
There she placed a sign, for anyone else in crisis.
"Please don't take your life today. The world is better with you in it," it read.
She returned to that place to change the memory it held into one of hope, she posted online.
"The girl who once stood here all those years ago was broken, unwell and couldn't see any way out. She was certain that the world was better without her.
"Little did she know that one day she would wake up excited for life. That she would know purpose, love and community.
"That one day the very thing that nearly claimed her life would be the thing she would use to help change the world.
"No matter how dark it feels right now, there is always hope."
