As promised, Marshmello and Demi Lovato dropped their new collaboration “OK Not To Be OK,” along with a video that has both of them looking back at younger versions of themselves.

The song was released in conjunction with World Suicide Prevention day, and Marshmello says the themes of the song are very “important,” and “very important to talk about it.”

“I think a lot of people, about negative feelings and negative thoughts that are affecting them are kind of scared to bring it up, scared to talk about it,” he told Apple Music’s Zane Lowe. “When in reality, they’re scared because maybe the person won’t relate or the person won’t understand, when in reality most of time the person that you could bring it up to, will most likely has felt like this or will understand or can relate as well,” adding, “So I think it’s very important to talk about it.”
