In a new PSA, Chicago Bears wide receiver Brandon Marshall discusses his experience with mental illness, as well as the social stigma around mental health — especially for men.

Marshall entered the NFL in 2006. His first few years in the league were riddled with arrests and violence. However, in 2011, he was diagnosed with Borderline Personality Disorder (BPD), a mental illness characterized by a persistent instability of emotions, relationships and behaviors. He has since become an advocate for awareness around mental illness.

In the video above — a partnership between Marshall’s Project 375 and Glenn Close’s non-profit organization Bring Change 2 Mind — Marshall talks about how he thought about mental health before his diagnosis.

“Before I was at MacLean hospital, if someone had said mental health to me, the first thing that came to mind was mental toughness, masking pain, hiding, keeping it in … that’s what was embedded in me since I was a kid. You know, never show a sign of weakness. And it’s funny, because now I know it’s the total opposite. It’s being able to have the strength to pick up the phone and ask someone for help.”

The campaign also includes a 30-second PSA, featuring Marshall, as well as Edmonton Oilers goalie Ben Scrivens, Passion Pit frontman Michael Angelakos and actor Wayne Brady. Check it out, below.
