When Alex Lewis came down with what seemed like a common cold, he never in a million years would have believed it would lead to him losing his arms, his legs and part of his face.
As his flu-like symptoms got worse and his body started turning purple, he was rushed to hospital to be told that, somehow, he had contracted Strep A - an extremely rare bacterial infection that causes toxic shock syndrome, where the body begins to attack itself from the inside out.
Watching this #AlexLewis documentary on C4. Had to read up on TSS on NHS website. Shocking what that can do to a body.

The documentary followed Alex around as he continued to adjust to his new daily life since he fell ill almost two years ago.
Viewers found the scenes very emotional, especially the ones involving his young son Sam.
Heartbreaking as a dad to appear alien to your child so they won't get close to you #AlexLewis

A son not wanting to kiss their own father... Truly heartbreaking. Genuinely cried at the end when he actually did ? #AlexLewis

They thought Alex - who needs constant care and assistance - was a true inspiration for accepting his situation as best as he can and not letting it get in the way of being a doting dad.

And they were truly in awe of his partner Lucy who said she has never even considered walking away from Alex because her love for him is just too strong.
She's still with him because it's true love. He's the same person. #AlexLewis

The show put things into perspective for viewers as to how fragile and unpredictable life really is.

The show finished with a beautiful shot of the family riding together in the countryside as they discussed how they hope to raise the £3million they estimate they will need to take care of Alex for the rest of his life.
Well, the family might be about to feel the full extent of the internet's power to do good as donations flood in for the Alex Lewis Trust, with some funding pages down supposedly due to high traffic.
