How can I speak again?’

The play contains strong language and explores issues of mental health, depression and suicide




★★★★ "The sheer courage and passion that has been thrown behind this intelligent production of a daringly experimental play wins out, and what lingers is its cry for love."

Time Out 

★★★★ "A heartfelt look at what it feels like to live with a profound disability, and just how isolating that can be."

The Guardian 

★★★★ “A productive insight into the problems of deaf mental health patients, forcing us to confront the fact that their experiences are rarely considered.”

The Spy In The Stalls 

★★★★★ "The defining feature of this production is its ability to utterly captivate and move its audience, making it essential viewing."
