The teenage son of disabled artist Alison Lapper had taken a cocktail of prescription drugs before his death, an inquest was told.
Parys Lapper - who appeared in BBC1s A Child of Our Time - had suffered years of mental health problems.
The 19-year-old had been bullied and abused in school over his mother's disabilities and had turned to drink and drugs as a way of coping.
However he became badly addicted to drugs and dropped out of school as his life spiralled out of control.
He was treated by mental health services but was discharged on August 1, just days before his death.
