Lauv's new single, "Sad Forever," is all about his battle with depression, but he's trying to turn that negative into a positive -- by using the song to raise funds for charities helping those suffering the same way. He says, “I wrote 'Sad Forever' at a time when I was extremely low. I was dealing with depression and OCD, but hadn’t really recognized or gotten the help I needed. Mental illness is something that is often times not apparent to the outside world. It’s an ongoing journey with ups and downs, and finding stability is a process that I’m still heavily working on.” All proceeds from streaming and sales of "Sad Forever" will go to international mental health charities.
