The top model who committed suicide — said to be the first celebrity victim of cyber bullying — had changed her medication to treat depression in the days before her death, Breaking Celebrity News has been told.

Television host Charlotte Dawson, 47, was found dead at her luxurious home in Sydney, Australia, on Saturday.

A source close to the Australia’s Next Top Model judge told Breaking Celebrity News: “Charlotte told friends that she had gone onto a new treatment plan which included a change in her anti-depressant medication.

"She did not seem directly effected by it, but We all knew that she was not in a very good place recently."

It is not known if the combination of drugs Dawson had changed to are known to influence suicidal thoughts, as some have been widely reported to.

Breaking Celebrity News has been told that Dawson hanged herself in a bedroom of her $1200-per-week oceanfront apartment.

While it seemed Dawson had the world at her feet, behind-the-scenes, she battled depression for decades.
