A British teen has taken the internet by storm after he created a video for his 16th birthday, showing his struggles with a brain tumour, epilepsy and hydrocephalus (excess cerebrospinal fluid in the brain).
"I have seizures most days," Lewis Hine wrote in his video, with a background picture of him in a hospital robe with crutches and being assisted to walk.
"My life is a challenge. But one I'm willing to accept."
Lewis, from Portsmouth, posted the video on his birthday last Saturday. It has since had more than five million views on Facebook.
"People say I'm disabled as if it's a bad thing, but I say I'm lucky," he wrote in the video.
He wrote that he was aware of his challenges and did not take anything for granted.
The teen, who was diagnosed with a brain tumour aged 17 months, founded 'Friend Finder', a project for children who missed a lot of school to meet up and make friends.
"Disability isn't a bad thing, BUT keeping silent about it is!" Lewis wrote in his clip.
He asks viewers to share the video, "to show the world it's ok to be different".
The video has had over 28,000 reactions, nearly 150,000 shares and around 6,000 comments.
