A desperate mum says she is living "every parent's worst nightmare" after her daughter went missing a month ago.
Shyanne-Lee Tatnell, 14, has been missing since April 30 when she was last seen crossing a bridge in Launceston, Tasmania.
Mum-of-four Bobbi-Lee Ketchell, 34, says she has barely been able to sleep or eat and Shyanne-Lee hasn't used her bank card or social media accounts since her disappearance.
