Stuart Gumm had a serious mental breakdown about four years ago.
Diagnosed with anxiety and depression, he often suffers panic attacks, no longer drives, and rarely leaves the house.
The 52-year-old from Talywain near Pontypool, in Torfaen, said the care provided by his 12-year-old son Carwyn has saved his life.
Carwyn is one thousands of young carers in Wales – and a charity says many more are not known to schools or local authorities.
Carers Trust Wales found up to 400% more young carers than expected at eight schools in a pilot study and they fear it puts the children’s life chances at risk.
