Los Angeles - Demi Lovato thinks it's "okay to have a mental illness".
The 22-year-old singer has been dealing with bipolar disorder for several years and has, therefore, launched her own campaign aimed at tackling the negative stigma against mental illness.
Addiction is addiction. Alcohol, drugs... You can become addicted to anything... Substances or even something as simple as sugar. It's not

She said: "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."
Mental illnesses of all kinds, especially addictions, are an epidemic that's barely talked about and people should try to become more

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.
She told PEOPLE magazine: "I watched him live a very unfortunate life because of the lack of access to treatment."
However, the Heart Attack singer - who's previously spent time in rehab - revealed she's doing well in her own battle against addiction and mental illness.
She said: "I'm doing really well. I'm successful, but most importantly I'm healthy and happy, and I do not let my disease define who I am."
Demi gave special thanks to her boyfriend, Wilmer Valderrama, 35, saying he's been "so helpful".
