Leah Croucher's devastated mother has revealed that she talks to missing posters of her daughter because the teenager isn't there for her to chat to.
Claire Croucher says there isn't "anything normal, anywhere, anymore" after Leah, 19, vanished in February.
"I can't go for walks by a lake because most of them have been searched," said Claire.
"I drive around and there's Leah's posters all over the place, everywhere I look. I stand at a bus stop and I talk to them because she isn't here for me to talk to her."
Despite emotional pleas from the Croucher family, as well as a £5,000 reward offered for any information which could lead to Leah being found, police have not found any trace of her since she disappeared in Milton Keynes.
Her parents earlier this year revealed in a heartbreaking interview they believe their daughter has been murdered and has not vanished deliberately.
Leah's heartbroken brother, Haydon, hanged himself a day after being discharged from mental health services on the the eve of the nine month anniversary of his sister's disappearance.
Haydon, 24, died as a result of multiple organ failure and never regained consciousness after his mother and sister, Jade, found him at his flat in Milton Keynes, Bucks., on November 14.
Speaking to the charity Missing People, Claire says that Christmas has been cancelled this year and the family will probably never, ever celebrate another one.
She said: "Christmas in this house used to be a joyful occasion.
"One year I did a crazy thing and decided that each kid was going to build their own gingerbread house and decorate it. I made my own gingerbread house, cut out the house shapes and iced them all together, had a little array of bits and pieces for them to decorate it with.
"It took a few weeks to do three houses, it was crazy. The kids loved it. They would all sleep upstairs in the same room on Christmas Eve, have like a little slumber party. They would still be awake at two in the morning.
"Christmas was always really, really good in this house. This year we're not going to do Christmas at all. There is no Christmas. I don't think there will ever be another Christmas.
"The impact Leah's disappearance has had on me is devastating. I go to work, I go and see friends and family but it doesn't mean anything - everything is hollow."
Turning to the double tragedy of losing Haydon, she explained: "Leah's sister Jade has tried to be positive and climbed a mountain to raise awareness. Her brother particularly struggled.
"He didn't cope at all with it and gave his own life because he could not cope with the lack of news, the lack of evidence, the lack of suspects, the not knowing where she is, has she chosen to do this to us all which none of us believe she would. And if that's the case, where is she? What happened to her?
"Those questions just slowly drive you insane and Haydon's mind wasn't able to cope with that. He was desperate to find answers. He took the role of protecting his little sister very, very seriously - he always did that from the minute she was born. They were always together.
"They touched so many lives Leah and Haydon and it has affected everybody and I just need those people that do know the information to come forward because they are not only helping me and John and Jade they would be helping everybody because the whole country wants to know where she is.
"Day to day life has changed, dramatically but it's kind of stayed the same, it's weird. We still get up in the morning, get dressed, go to work but then we come home and there aren't any more family meals. Feels like it's done from a distance. I just need people to keep looking."
