As Tina walks onto the stage in front of hundreds of people she is beaming.

She's collecting her British Sign Language (BSL) certificate which is the culmination of a journey that began with tragedy.

"Learning BSL has helped me say words that I cannot speak," she says.

In 2018, while returning from a holiday, Tina fell down a flight of stairs and was in a coma for six weeks.

The accident caused a traumatic brain injury that dramatically changed her life, leaving her struggling to speak.
