Renewed fears for Olivia Newton John's daughter after emotional social media post.

The daughter of Australian singer and actress Olivia Newton-John has sparked renewed concerns about her health and wellbeing after writing a rambling post on social media about online trolling.

Chloe Lattanzi, 30, posted a video on Instagram on Tuesday to hit back at her “haters” who accused the singer of photoshopping her images, detailing how much anonymous criticism can affect her.

After writing her thoughts, Lattanzi made her account private.

“With new followers comes new weirdos,” she began the post. “I am such a sensitive creature you have no idea. Please if you don’t know me don’t make comments like you do.”

Lattanzi went on to claim that trolling makes Instagram a platform that is “less fun” and “scary” to engage in.

“I’m not dumb. I’m not a drug addict, and I have a kind heart. I know I shouldn’t care about random people who have their own problems so they decide to take it out on me, but I just don’t get it.

“I know I’m not dumb or vapid or fake... all I ever give people is love and kindness and it’s so weird that there are people out there who want to bring others down."

Lattanzi acknowledged her reason for publishing the rant was to make public how much random comments from strangers had an impact.

"I just wanted to get real and bring to light the real effects of this problem. Everyone gets hate, and that's sad.

"I don't believe the things they say, I know I'm not dumb and I know I have talent. But wow, the darkness from others can really affect me. I wish you all the love, I wish the world was different," she wrote.

The singer and face of Equestrian Designs has been the focus of public attention and concern since she was just a teenager, battling an eating disorder in front of very public and prying eyes.

Since then, Lattanzi has been open with her battle with what she calls body dysmorphia, highlighting a certain difficulty that comes with navigating public spotlight and body image.

Just last month, the 30-year-old appeared in an episode of The Doctors to reveal how struggles with body image have enveloped her youth.

"When I was in the height of my body dysmorphia, I had a whole bunch of fillers,” she said on the episode.“I’ve had that all removed from my face because I like the way I look naturally."

“I look back at myself and I as a teenager and I’m like, ‘What a beautiful young woman,'” she said. “What was I thinking? Why was I so insecure?

How does Mia Freedman deal with her own haters? Post continues after video.

“I think so many young girls are going through body dysmorphia — we’re constantly told how we’re supposed to look via Instagram and filters,” she said. “There’s constant pressure for us to look perfect.”

Lattanzi's high-profile mother has largely kept quiet on her daughter's struggles, telling 60 Minutes in September that being a child of a person in the limelight is a difficult feat for anyone to handle.

"I think it's hard to be the child of a person in the limelight, I really understand that," she told the program. "There's privilege but there's also other things that come along with that,' she added."

Despite that, Newton-John told the program her daughter is "happy and working" and "in a good place" at this point in her life.
