The 22-year-old singer launched her own campaign aimed at tackling the negative stigma against mental illness, reported People magazine.
"I just think mental illness is something people need to learn more about. I want people to know it's okay to ask for help and it's okay to have a mental illness," she said.
The chart-topping performer, who was diagnosed as bulimic, bipolar and addicted to drugs and alcohol in 2011, explained that her father, Patrick, suffered from similar illnesses before he passed away in 2013.
