An ambulance worker and ex-policeman fighting for his life in intensive care against coronavirus sent his family a heartbreaking text before he was put into an induced coma.
Jack Frost, a medical technician for East of England Ambulance Service, had been facing the killer bug head on responding to calls since the beginning of the outbreak.
When the 63-year-old, from Cambridge, suddenly fell ill he put it down to exhaustion from working long hours, but his bosses told him to self-isolate when he developed a fever.
"He was just feeling a bit under the weather and then he had a couple of days off and it really hit him, he was feeling really unwell," his daughter Alex, 25, told CambridgeshireLive.

A couple of days after he began his quarantine dad-of-five Mr Frost was taken to hospital struggling to breathe before being taken into intensive care.
Alex said she got a call from her brother - a trainee paramedic - saying her dad had initially been taken to hospital and the siblings assumed it was a precaution.
"But then we thought, he's an EMT, he would never call an ambulance if he didn't need it," she said.
"It was obviously really bad. He was struggling to breathe."
After a day or so in hospital Mr Frost appeared to be recovering, but then "all of a sudden we all got a text from him saying 'I love you' and that was it", said Alex.
"He got taken into intensive care and we haven't heard from him since, he was put straight into a coma," she added.
The time-span from when Mr Frost first felt unwell began to going to hospital, testing positive and then being moved to ITU to be put on a ventilator was around five or six days.
He is currently being cared for at Addenbrooke's Hospital, on a Neuroscience Critical Care Unit which has been opened up as a critical COVID-19 ward.
His wife Karen, 57, has had pneumonia before and is more susceptible to the virus, so Mr Frost had moved out of the family home into a nearby Travelodge prior to falling ill.
He had encouraged his family to stay at home as much as possible and not put others at risk - though told them people are constantly calling for ambulances that don't need them.
Alex said not seeing her dad has been "horrible" and her mum "feels guilt" because her husband visited her every day when she was in hospital with pneumonia and "she now can't do the same for him".
Alex said Mr Frost "would do anything for anyone, he's really funny and always cracking a joke".
"Even when things are really bad he's the person who keeps a level head and raises positivity."
Alex usually splits her time between Nottingham, during the week for work, and the family home in Cambridge, while her sister lives at home with their parents.
Mr Frost also has three sons, one who is studying to be a paramedic at university in Hatfield and cannot return home during lockdown.
While his two oldest sons live in Southampton and on the Isle of Man, which has now closed its borders.
"We're all pretty split up," said Alex, "and my dad's brothers live in Wales, but we talk every day and everything.
"People say oh well you've all got each other, but it's difficult when you can't really be there for each other."
However, Alex said there's been an "outpouring of love" for her dad since he went into hospital.
He previously worked as a Met Police officer and a Royal Engineers diver for the Army, before becoming an ambulance technician a decade ago.
His daughter said "all his old colleagues" as well as people he's treated as an EMT have been in touch to wish him well.
"There's so many people saying how close they feel to him and the impact he's had on their lives and everything, and I'm just like that's probably more people than I've ever met in my life.
"Nobody's got a bad word to say about him, I think a lot of people are shocked it's happened to him."
Alex is hoping to raise some money for NHS staff at Addenbrooke's who are caring for her dad and other coronavirus patients - check out her fundraiser here.
"They're doing so much for not just my family but for so many people that are relying on them", she explained, "and if I can spread the word a bit.
"We really want to spread my dad's message, because before this he was really trying to get people to stay at home, and say it won't discriminate because my dad was healthy before this.
"We just want to spread what he was trying to say and the impact of people's actions."
"There are people doing 14 hour shifts, with a 15 minute tea break, in critical care.
"If by raising this money we can get everyone on the ward a hot meal and a half hour break that would be amazing," she added.
