Sir Chris Hoy is among the celebrities backing a new social media challenge aimed at tackling mental health stigma.
The former Olympic cyclist is supporting the Wee Pink Dot challenge from SAMH.
The charity said people living with mental illness often feel like the world is disappearing around them.
Its challenge asks people to film or photograph themselves drawing a pink dot on their hand as a “visible reminder to show up for people with mental illness and call out stigma”.
Supporters are asked to share their video on social media, tag SAMH and nominate three people to continue the challenge.
Olympian Duncan Scott, Paralympian Sammi Kinghorn, broadcasters Jean Johansson and Des Clarke, poet Len Pennie, and podcaster Sean McDonald have all backed the campaign.
Ciaran McBride from Ayr has struggled on and off with his mental health since he was a teenager and is supporting the Wee Pink Dot challenge.
He said: “I first experienced depression when I was about 18, and although I initially accepted professional help, the reaction to this from others made me feel guilty and ashamed – so I came off tablets and didn’t go back to the doctor.
“If I had a broken bone, I would have been supported to get better, but because it was my mental health, it felt like that support just disappeared.
“I have found my own coping mechanisms over the years, and now attend a running club almost religiously, which helps massively. It gives me time to talk and to let go, and even when things are hard, we’re able to show up for one another.
“I’m supporting the Wee Pink Dot challenge because mental health shouldn’t be something we ignore. We all need to show up – for ourselves, and for those around us.”
Speaking during the launch at the Glasgow Science Centre, presenter Jennifer Reoch said: “Stigma doesn’t just hurt feelings, it shapes lives. We all have a part to play in creating a Scotland free from mental health stigma.
“That’s why I’m wearing my Wee Pink Dot with pride – it’s a reminder to show up for friends, family and anyone else affected by mental health problems.”
If you believe in a Scotland that shows up, join our campaign. Take the Wee Pink Dot challenge
Billy Watson, chief executive of SAMH, said: “Too often, people living with mental illness feel like the world is slowly disappearing around them.
“Even the healthcare system, which is set up to support us, can feel out of reach.
“It isn’t always intentional, but as a result of stigma, opportunities shrink, support becomes harder to access, and colleagues and loved ones step back.
“Connecting with others can make all the difference.
“That’s why we’re calling on people in communities across Scotland to show up, be there, and stay visible. If you believe in a Scotland that shows up, join our campaign. Take the Wee Pink Dot challenge.”
