We're big fans of the fighting force that is Denise Ryan.
Since being diagnosed with Lyme disease, the Rathfarnham woman has really come out swinging – organising Into The West screenings, selling T-shirts and dreaming up mad schemes to help her raise the cash she needs for treatment in the States.
Yesterday, her story was covered in a Humans of Dublin post. And to say it will stop you in your tracks is an understatement.
It's a story of how the everyday can suddenly become a battle to survive, and how that battle can unearth aspects of someone's personality that neither they nor anyone else knew existed.
