We first met Abbie when she starred on Matt Agnew's season of The Bachelor and made it all the way to the final two.
But seeing as she was portrayed as a sex-crazed villain, it didn't take long for the internet trolls to come hard and fast. By the time the finale was about to air, Abbie admitted she even had suicidal thoughts.
"I still struggle with all the trolling. I still struggle with things. I try to take care of my mental health," she confessed on the TV RELOAD podcast in February 2021.
"I go to therapy once a week. It's still very hard. A year and a half in this isn't very long really. And I was 23 when I got all that trolling."
Since her Bachelor days, Abbie has starred on Bachelor in Paradise and I'm A Celebrity... Get Me Out Of Here!, the latter of which she won in 2021.
Growing up in foster care throughout her childhood, season six Bachelor star Brooke saw and experienced things no child should ever have to endure.
But the incoming 2021 Bachelorette has been a vocal advocate for all things mental health and is also an ambassador for R U OK Day.
"Playing sport also keeps me active, so that has helped me stay on top of my mental health, every time I feel overwhelmed or stressed, I go for a walk or kick the footy," she explained.
"It always makes me feel better to get out of the house or workplace for a bit. I find doing the little things to make you feel better, can change your whole mood. Like treating yourself or planning a date night, something a little spontaneous but nice."
Bryce Ruthven and Melissa Rawson
If you watched MAFS in 2021, you'd always hear something about these two.
When the show ended, Bryce explained that he was medically diagnosed with severe anxiety and takes CBD oil to manage it.
"I haven’t been in my normal routine, I have regularly struggled to sleep & have felt on edge almost everyday," he explained in July.
The couple, who are expecting twins, also shared a post in honour of R U OK Day 2021.
"You can’t underestimate how important your mental health is, sometimes a simple question can mean more than you think. Ask someone.. R U OK?" Bryce wrote on Instagram.
When Jake starred on the eighth season of Married At First Sight, he was open about his former mental health struggles and how it led to creating his own charity, Outside The Locker Room.
However after his reality TV experience and relationship breakdown with Sophie Guidolin, the former AFL player was open about how he tackled his demons.
"If you had of told me 12 months ago that I would be living in Queensland, working on a new career path, vegetarian, no intoxication and all of this after going away to spend 4 weeks living with monks with no distraction to find myself once again, I would have told you to get stuffed and you’re delusional," he wrote in September.
"At this very moment I am the happiest I have ever been. I’m the best version of myself and I am so proud of the soul searching and confronting work I have done on myself to feel content, happy, grounded and at peace."
Back in 2020, Natasha married Mikey Pembroke on MAFS and confessed that the five weeks of filming spiralled her into "the worst mental state that I had ever experienced". She added that the public backlash that followed was even more damaging.
"Life is filled with tests and I needed something like this to shift me out of my comfort zone. I no longer regret my time on #MAFS but cherish the lessons and the experiences," she wrote on Instagram one year after her reality TV experience.
Since, Natasha has quit drinking alcohol and has found love with fiancé Gary Green.
Natasha's MAFS bestie and co-star Tash also struggled mentally after filming and the season airing.
In an Instagram post shared in 2020, Tash slammed her on-screen wife Amanda Micallef and shared that she decided to go public with her experience after receiving lots of questions from American fans.
"I want people to know what it was like for me, if they are curious or can’t understand through the editing and vilifying, what it was like to be constantly asked why you don’t want to be around someone that feels they are owed physical affection, love and fame no matter how many times you have explained, kindly, that you do not feel comfortable giving them that," she penned.
In 2018 Married at First Sight star Tracey Jewel revealed she had admitted herself into a mental health clinic, after overdosing while stranded in Europe.
"I’m not someone who has a history of depression, but I started getting help in April because the psychologist said I might have post-traumatic stress disorder because of everything I’d been through."
Since then, Tracey has found love with husband Nathan Constable and welcomed baby son Frankie.
"Now more than ever it’s important to check in with your loved ones.. and yourself! @ruokday encourages all of us to not only ask r u ok but to listen, point them in the right direction and offer support if we can. We are all in this together," she wrote on R U OK Day 2021.
