After her son Cody Bergemann died in a car accident in Gympie, his mother made a Facebook appeal.

A grieving mother has recalled the moment she learned her teenage son died in a vehicle accident, asking others to embrace their loved ones tightly.

Katherine Bergemann-Cook said in a video posted to Facebook that she received “the worst news of my life” late Wednesday night when she learned that her 19-year-old son Cody Bergemann was died in a car accident just before midnight in Queensland’s Sunshine Coast region.

According to the Courier Mail, Mr Bergemann rolled his car on Neerdie Rd in Glenwood, and police are currently investigating the circumstances of the accident.

Ms Bergemann-Cook expressed the agony of knowing she would never see her child again in a distressing four-minute video.

‘I saw the worst thing which I will remember for the rest of my life but at least I got to say goodbye to my boy,’ she said.

‘There is one thing I want and I can never get: I want my baby boy back.

‘I’m not going to get that one hug again, I’m not going to get that one kiss, I’m not going to be able to jump in his bed and … have a chat about his weekend was or what he was doing.’

She then expressed gratitude to Mr Bergemann’s friends, as well as her own friends, family, and’support network,’ and revealed that Mr Bergemann’s younger sister slept in her brother’s bed on Thursday night.
