UPDATE, 11.14am, Tuesday: There are no new updates on the investigation into the disappearance of Sharon Edwards, police say.
Coffs/Clarence Detective Inspector Darren Jameson confirmed the investigation was continuing.
"THERE'S so many things I want to tell her, I just hope I get a chance to do that."
These are the poignant words of Joshua Edwards, the eldest son of missing Grafton school teacher and mother-of-three Sharon Edwards.
The search for clues into Mrs Edwards' disappearance is now in its eighth day.
"With each day that goes past it gets harder and harder," Josh said.
"Every phone call we get we are just praying for something."

Josh said he last spoke to his mum on her birthday, about a week before her last confirmed sighting between 10pm and 11pm on Saturday, March 14.
"She was at the airport about to fly home, and I wished her happy birthday," he said.
"She said 'I love you my boy, I'll catch up with you in a few days'.
Mrs Edwards was reported missing by her estranged husband John last Tuesday, after she failed to show up for work at Coutts Crossing Public School on the Monday.
"I've been calling the police every day for updates and asking if there's anything I can do. They said they'll call me if there's anything new, but I can't just sit here and not do anything," Josh said.
"Sitting on your hands is the worst thing. We just want some good news, or any news really."
The 29-year-old said he and his brothers had always been very close with their mum.
His brother Zac had breakfast with their mum in Coffs Harbour the day she went missing, and the weekend before Sharon had spent in Brisbane babysitting her son Eli's daughter, whom she doted on.
"She loves being a grandmother and she's amazing with her," Josh said.
"She always wanted to come by the house, and would ring us several times a week," he said.
Josh said the family was sticking together and trying to remain positive throughout their ordeal.
"Certain things go through your mind, but we're all staying positive until the police tell us otherwise," he said. "Dad's not real good... he's probably taken it the hardest.
"But she's got a lot of friends and a lot of support. We've all had heaps of messages and phone calls and everyone's sharing heaps of different articles on her on Facebook.
"It doesn't matter where she is or what the reason is, we just want her to come home. We want to see her face again."
Anyone with information on Mrs Edwards' whereabouts should phone the Grafton police Station on 6642 0222 or Crime Stoppers on 1800 333 000.
