A woman's positive posts on social media have been published on billboards across the UK and seen her amass thousands of followers.

But for Coco, the real measure of success is the number of messages she receives from people who say she has saved their life.

"I wanted to end my life. I visited your page and it's given me a reason to live," read one message she woke up to one morning.

Another said: "I haven't had anyone to talk to, and ended up in hospital trying to hurt myself. Looking at your page has made me feel at peace."

The mental health activist, from Cardiff, posts positive affirmations on her Talk to Coco Instagram account, including those which read "you are enough", "you are loved" and "you are worthy".

"Mental health is who we are, it's part of us like our hair colour or our eyes, it's not a bad word and that's important to remember." she said.

Coco said her passion for mental health started as she "couldn't fake" how she was really feeling any longer so started posting on Instagram to express her feelings.

The 30-year-old said: "The response was magic. I felt human again, I felt recognised and acknowledged for who I really was.

"It gave me a feeling of euphoria, to be able to be me and be loved - was something I never imaged could be.

"Having ADHD [attention deficit hyperactivity disorder] makes me need validation and acceptance and it was something I never truly understood until I was so honest with myself."

Another inspiration has been the death of one of her friends.

"My friend called out for help for years - she had an awful life and she saw her mother get killed as a child," said Coco.

"She was the most intelligent person I know. Amazing in school, graduated university with a degree in law. She seemed OK, because educationally she was doing well.

"However, she took her own life."

She added: "If someone tells you they need help, believe them, I guess it can always be too late and then people want to start change."
