Broken-hearted Hughie (21), revealed last night that the situation has worsened for his sister after she developed a double bout of pneumonia.
The TV star revealed that doctors have told the family that the next two days are “crucial” in her fight against the virus.
In an emotional Instagram post,
Hughie wrote: “People don't understand the danger and seriousness of the situation the world is in.
“I completely understand the reasons for people's frustration and disappointment with losing out on holidays, weddings and events they planned for months.
“I understand the economy and mental health etc are being effected, I completely understand all that and I also feel the same frustration.
“I'm going through heartbreak and haven't a way to distract myself because of lockdown again in Ireland.
“It's been very, very hard and a time I won't ever forget but we need to start looking at the bigger picture.
“I can't see family, I have around ten family members with Covid, my sister is very sick but also I understand we need to stand together and get through this.
“My sister is so sick in hospital the past week with Covid, she’s got double pneumonia and the Dr said that this next two days are crucial."
He continued: “She’s 19 and has a baby, it’s nothing to joke about.
“And complaining you can’t go out on a night out for Halloween.
“I get it, I understand it’s hard, I completely do, but when someone you love is deteriorating in hospital, you realise what’s important.”
The star urged followers to take level five restrictions seriously, adding that panic buying is "f*****g selfish."
“How about this year we teach other the importance of family rather material things for Christmas?
“How about we don't focus on spending loads of money and maybe help local or small businesses with our trade and just enjoy family time and kids to do the same?
“Instead of that people are out yet again panic and bulk buying, my local supermarket has no frozen food or milk even though Level 5 was only announced yesterday.
“People are already out buying everything in front of them when there is (sic) others who can't afford to be out buying all their Christmas clothes and toys.
“And now there is things even sold out online because of how quickly people have started buying.
“People need to get a grip and stop being so f*****g selfish and stop with all the wiping out of the shops and having fights and stuff to get bikes etc and complaining 24/7 about the pubs being closed.
“You can in time go back to normal life but for now this is what it is, you have to remember that.”
Hughie also told followers who are struggling with mental health issues to drop him a line.
“Anyone who's dealing with mental health problems can message me and I'll always respond when I see them,” he added.
