At the age of 20, Jonny was diagnosed with schizoaffective disorder, a combination of schizophrenia and bipolar, and later began making films on YouTube about the condition that have been watched by millions of people.
He now speaks publicly about living with mental illness and has also produced and presented documentaries on BBC Three and Channel 4 on the subjects of mental health and suicide.
His 2014 social media campaign with Rethink Mental Illness to #findMike, the man who talked him out of jumping off a bridge when he was suicidal, went viral and led to Jonny becoming a prominent spokesperson on the subject of suicide.
Jonny now runs youth mental health charity, Beyond, a grant-giving organisation providing mental health support to young people, their families and teachers.
