Hiding my psychosis for 10 years from the age of 12 Luke Watkin was in year eight at school and alone in a corridor when he first heard a strange noise.
"I heard what sounded like a train brake, followed by a metal on metal noise.
"It was just something completely out of the ordinary. It was a bit of a shock to the system, something I just couldn't understand or really process.
"My experience at the time was quite terrifying."
It was his first experience of the mental health condition, psychosis. Luke was 12 years old. BBC News
