A 10-year-old girl from Plymouth who suffers from Myalgic Encephalomyelitis (M.E.) has reached thousands of people across the world through a video posted onto Facebook, where she tries to tackle stigma against the condition.
Shannon Tiday says she is angry about a new and controversial treatment, which suggests M.E. can be treated as a psychological illness.
She's had messages of support from sufferers in Europe, Canada and even Australia
Shannon has been left practically housebound after developing M.E. - a disease with symptoms of chronic fatigue - meaning her childhood is very different from her peers.
Shannon's mother also says her daughter has faced accusations that the condition is all in her head.
Shannon made her Facebook video after learning about a private treatment called The Lightning Process - which suggests her condition can be improved through psychological treatment.
However, many people have claimed that The Lightning Process has been successful.
What is the Lightning Process?
A course that teaches people how to use their brain to improve their body's health.
It includes simple exercises and movements help encourage recovery.
It is not available under the NHS
Meanwhile, the NHS recommends a variety treatments for M.E.
CBT - Cognitive Behaviour Therapy.
Graded Exercise - In a structured programme.
Medication - To control/manage pain
Shannon hopes that by speaking out, she can one day make a difference.
