Karen Sutton, a widow coach from Gloucester, said social media is helping to bring conversations about grief into the open.
“I think social media is opening up conversations that previous generations often kept behind closed doors,” she said.
“It’s helping normalise grief and reminding people that there isn’t one ‘right’ way to experience it.”
She said platforms such as TikTok can help people “find community” and “reduce feelings of isolation”, but warned against relying solely on online support.
“My advice would be to see it as one part of your support network, not your whole support network,” she said.
“Alongside the online connections, make sure you have opportunities for real human connection too.”
Mulcahy said sharing her story is ultimately about reaching the person she once was: a young woman facing unimaginable loss and unsure how she would survive it.
“I would just say to her, ‘you’re going do a really good job’,” she said.
“We often question our strength and our capableness.
“Actually, humans are so resilient.”
