Razzak Mirjan founded Beder in honour of his brother, who took his own life aged 18.
He said the “worst day of my life” had given him “perspective”.
“It makes you realise what’s important, and now it’s our chance to try and do good in his name and to keep him with us,” he said.
“To me, it’s my therapy.”
He said he hoped the shirts would help start conversations about mental health.
“Football is an amazing way to raise awareness and bring people together,” he said,
“[It’s] an incredible opportunity for visibility, for conversations to be had and to raise awareness.”
A key initiative of Beder’s is to fund six free online therapy sessions.
They’re available to anyone who is 18 or older, with more than 500 online sessions having already taken place since mid-2023.
