Nicola Bulley's parents have returned to a bridge near the scene where she vanished, and told their daughter: "We pray everyday for you".
The mum-of-two was immediately categorised as a high-risk missing person when she disappeared on January 27 in St Michael's on Wyre, Lancashire.
Lancashire Police said that she had "specific vulnerabilities" relating to alcohol in an unprecedented revelation yesterday.
It came as the force faced increasing scrutiny over their handling of the case, and have since faced backlash for divulging details about Nicola's private life.
On Thursday two new messages had been penned on yellow ribbons of hope, attached to a bridge near the footpath where Nicola was last seen.
They were left by Nicola's parents, Ernie, 73, and Dot, 72 and her younger sister, Louise Cunningham.
The message from her parents read: "We pray every day for you. Love you, mum and dad xxx"
Another from her sister said: "Nikki, please come home. I love you, Lou xxx"
The 'bridge of hope' set up by friends and family over the weekend has been inundated with notes from local people and school kids.
Louise also shared a drawing of a woman covered in yellow hearts on her Facebook.
The caption read: "Nikki you are outrageously loved."
It comes as police came under scrutiny yesterday for sharing the mum-of-two was categorised as "high risk" due to "a number of specific vulnerabilities".
At the time, they did not elaborate and sparked further speculation despite trying to use the press conference to squash any unhelpful theories.
Hours later, police then put on Facebook that " in the past suffered with some significant issues with alcohol which were brought on by her ongoing struggles with the menopause".
They added that these issues had "resurfaced in recent months".
This has sparked outrage from MPs and confusion from former police officers.
Martyn Underhill told Sky News this morning that he had never "seen such a level of detail" released in a missing persons case.
He also questioned why officers were releasing it now.
Speaking to Kay Burley, Mr Underhill said: "You can understand why some people are saying it's victim blaming to protect their own reputation.
"I can't see how it progresses the case any further forward now we're three weeks in, to be frank."
The statement sparked fury from MPs.
Labour's Stella Creasy said: "The decision to disclose this level of detail on a missing person's private life, with no evidence that this is assisting in finding her, is deeply troubling.
"The police need to be much clearer as to why any of this helps find Nicola Bulley or support this investigation."
Conservative MP Alicia Kearns said she was "deeply uncomfortable" with the police releasing details about Ms Bulley's "so called 'vulnerabilities' on menopause and alcohol".
"I struggle to ascertain how this will assist Police in their search & investigations," she wrote, adding, "I do see how it would assist those wishing to victim-blame or diminish."
