A young paramedic who was "adored by all who knew her" died suddenly on Monday evening.
Charlotte Cope, 23, worked for the Welsh Ambulance Service, who described her as a "much-loved" member of staff.
Based in Gelli in the Rhondda, she qualified as a paramedic in 2018 and had worked for the service for two years, Wales Online reports.
Paying tribute to his friend, fellow ambulance worker Connor Quinn described her as a "very promising and proud paramedic."
He said: "Charlotte Louise Cope, my close friend and colleague was tragically taken too soon at the young age of 23 on April 12, 2020.
"A very promising and proud South Wales paramedic adored by all who knew her, she had carried the weight of the world on her small shoulders in silence for far too long.
"Her heartwarming nature could be felt by everyone in her presence to which she was completely oblivious, this made her all the more special.
"I think I am speaking on behalf of all her friends and colleagues when I say we are heartbroken and devastated and we all miss and love you so much.
"To her she was just another ordinary girl, but to us she was that one little bit of happiness and cheer we are often looking for within the ambulance service especially at these unpredictable times."
Jason Killens, chief executive at the Welsh Ambulance Service, said that the service is supporting Charlotte's colleagues and family following her death.
He said: "It is with a heavy heart that we can confirm the sudden death of one of our paramedics on Monday evening (April, 13, 2020).
"Charlotte Cope, who was based in Gelli, Rhondda Cynon Taf, was a much-loved member of the Welsh Ambulance Service family having joined the organisation in 2018 after qualifying as a paramedic.
"We would like to extend our deepest sympathies to Charlotte's family, who we are supporting through this difficult time.
"Support arrangements are also being made for Charlotte's colleagues across our organisation.
"I would ask that we give regard to the wish of Charlotte’s family at this very sad and difficult time and respect their privacy."
A fundraiser has been set up to help cover the cost of the NHS worker's funeral and support her grieving family.
The GoFundMe page, which was set up on Wednesday night, has already raised more than £10,000.
