Charlotte and James' story
Charlotte will never forget the day her mum, Lorraine, had a heart attack - her life, and that of her brother James, changed forever.
"Being the older one," she says, "I had to be strong for my brother. But all I could think was, how am I going to tell James if mum dies?"
Lorraine's heart failure affects the family on a daily basis as she can't do much by herself. She has to stop to get her breath back when walking up the stairs.
"We're not a normal family anymore," says Charlotte. "Every day I wake up and make sure she's awake. I check that she has her pills and that nothing's too stressful for her."
She knows heart failure is incurable, but Charlotte still has hope. "The British Heart Foundation have been a massive help to us," she says. "We know first-hand what they can do - without them we probably wouldn't have a Mum."
