Watch Passion Pit Singer Michael Angelakos’ Bipolar Disorder PSA

'It stung for a little bit and then everything improved,' says Angelakos.

Passion Pit singer Michael Angelakos has been open and honest with fans about his struggles with bipolar disorder. When the band had to cancel a tour in 2012 to allow him to work on his mental health, Angelakos talked about how debilitating the disorder can be.

According to Half Of Us, "bipolar disorder is a treatable condition and the majority of people with this condition respond well to medication and therapy. It’s important to get help and stick to a prescribed treatment plan."

To encourage others to get help, Angelakos has joined some NFL and NHL players and comedian Wayne Brady in Bring Change 2 Mind and Project 375's joint campaign, #StrongerThanStigma, which focuses on the importance of men not being afraid to talk about their mental illness, which 375 says affects 1 in 4 adults.

In a PSA for the campaign, Angelakos talks about how talking about mental illness has actually improved his life. "Once I started really just accepting my mental condition, it stung for a little bit and then everything improved," says Angelakos, who was diagnosed at 18.

"And when people ask me what it's like to live with bipolar, you just have to adjust and figure out exactly how you're going to live you life the way you want to live it and achieve what you want to achieve. But you can only do that once you get help."

Angelakos is just the latest celebrity to open up to his fans about a struggle with the disorder. Earlier this week, Fall Out Boy bassist Pete Wentz discussed his long battle, last year it was revealed that Chris Brown also suffers from it, and Demi Lovato even let cameras in and discussed her experience with bipolar disorder in her documentary, "Demi Lovato: Stay Strong."
