"I was hijacked to come here by husband and case worker," she recalls.
"I said, I'm fine, I don't need any help. Clearly I did.
"But walking in those doors, I went, 'Oh, wow'. Literally the atmosphere hit me the minute I walked through the doors, an atmosphere of care and people who knew what they were doing, and who were here to just envelope you with love and support.
For many others — Khoury among them — it's been a home to say goodbye.
Her daughter, Lili Mantoura Khoury, was 4 when she died at Bear Cottage last year. She spent her short life battling severe epilepsy, her little body constantly seizing.
Bear Cottage helped the single mum get some desperately needed support and relief, even though she didn't think she needed it at the time.
And it still does. Both Saras came together for "Mother's Camp" in May, an almost "girls trip" away for a week that starts on Mother's Day and involves pampering, social outings, and plenty of time for reflection.
While other mothers at the camp had their children with them, Khoury didn't have Lili — and walking through those doors without her was tough.
"It's so nice to sit with a group of people that totally get you," she says.
"People can say they understand what you're going through, that they're tired too, but no, you don't get it. You don't wish this on anyone, but you don't get it, unless you're walking in these shoes.
"To come to Bear Cottage and sit with a group of people that totally get you, you feel like yourself, because you lose a lot of yourself when this happens."
Bear Cottage is one of only three children's hospices in Australia, but it's nothing like a hospital or what you'd imagine palliative care to be.
Its rooms are set up to make families feel like they're at a holiday home and, only a short trip from Manly's beautiful beaches, they almost are.
Only this holiday home is equipped for 24-hour paediatric care and that specialised paediatric care is exactly what provided Khoury with precious final memories she'll forever cherish.
"Lili was having an okay day and one of the beautiful nurses, Megan, came up to me and said, 'Lili likes going to the beach doesn't she? Right, well we're taking her to the beach'. I said, 'How are going to do that?'
"She said, 'Oh, we'll do that', and I'm thinking oh my god, what if something happens?
"I was very worried, telling all my family, and the next thing everyone is organising it."
Lili was put in a wheelchair — one she'd had for just four weeks because it took "forever" to get through the National Disability Insurance Scheme — and was driven very slowly down to Shelly Beach.
At the beach she was put in a special water chair she loved using at the cottage.
"We got her out of the wheelchair, put her in the water chair, and we just sat near the water," she says.
"It was just amazing. Just to know she was laying there in the sun, looking like a celebrity — because everybody in hospital and Bear Cottage knew Lili as the best-dressed child.
"They said it's going to happen soon, what do you want?
"I said I just wanted her in my arms. They put her in my arms, we played her song, Justin Bieber's Purpose.
"She loved Justin Bieber and it was very fitting because the first line of the song is, 'I feel like I'm breathing my last breathe', and that's when she passed in my arms.
"You couldn't have asked for a better way."
Staff asked if Khoury wanted to bath Lili again. True to Lil's style, she only wanted to dress her.
