"This weekend we lost the fight for my daughter's life against depression, trauma, PTSD and drug addiction that we have been fighting since we got her back from America through emergency repatriation [Department of Foreign Affaird] but broken," her father's tribute began.

"She fought hard against her demons as we all did side by side next to her and picking up the broken pieces over and over again but she could not fight any more and we lost her.

"As her dad I am proud of her beyond words as she is my hero, my daughter and my best friend that I love so so much. She is no longer hurting now with the universe wanting their angel back.
