Sitting on her lounge, she began her message with news about her twins, which she revealed are "doing fantastic" and have put "on weight, as they should be."
The boys, born prematurely on October 16, are having "bigger feeds" and eat "every three hours" – and now weigh 2.7 kilos.
Following the good news, she turned her attention to her battle with sleep deprivation - which is taking a toll.
"The sleep deprivation is just next level," she said, visibly emotional.
"You are told by everyone that, 'enjoy your sleep now, you're not going to get any sleep when the baby arrives '... and yes, that's very true, and I'm aware of that."
Liss continued to say that nothing can actually prepare you for how it feels to be running on little to no sleep as a mother to newborns.
Over the past few nights, she and her partner, Bryce Ruthven, have been "pretty catastrophic" because the twins have only been sleeping for "five minutes here and there."
“You just sit there going, ‘I don’t know how I’m going to do this’ or ‘I don’t know how much longer I can take.’ But we do it because we love them because they are the best thing that ever happens to us,” she said in the video.
Of course, Liss also noted that she is incredibly happy to have her twins home and is grateful she has strong support systems with family and friends offering to take care of the boys so she and Bryce can have some sleep.
The former Married At First Sight contestant shared a lengthy caption to help other parents feel less alone with their journey alongside the video.
"Not every day is a good day in parenthood or life in general. No matter how many happy posts, stories, reels, partnerships that you may see, we tend to only post the good or glamourous," she began.
"So, I'm posting this because I know I'm not alone, and there are others out there that can relate to my experience and could potentially give advice and a kind word to someone reading the comments here… to know they're not alone.
She dedicated the rest of her message to encouraging struggling parents to reach out to support systems.
"I'm putting my hand up to say I am struggling and that parenthood is tough. Sleep deprivation is torture. But having babies you love with all your heart, a good partner/people in your close circle, a GP to discuss a plan and great followers and online support, I know what I'm feeling is only temporary," she assured.
She finished off by linking to Beyond Blue and Panda Australia, two organisations dedicated to assisting with mental health issues and depression in Australia. You can call Beyond Blue for support 24 hours per day on 1300 22 4636.
