Schools must do more on mental health, say School Reporters
According to the School Report research, 70% of teenagers experience negative feelings.
Grace, 16, has been bullied for the past nine years, has moved schools twice, struggled with suicidal thoughts and taken medication for anxiety and depression.
At one point, she says, "there was no-one to turn to in the school and I felt so low I didn't want to go on".
According to research for BBC School Report, half of teenagers with mental wellbeing issues try to cope alone.
