"Depression is the constant feeling of being numb. Being numb to emotions, being numb to life.
"You wake up in the morning just to go back to bed again."
The reality star also shared a collage of nine celebrities who have all died by suicide, including Robin Williams, Kurt Cobain, and Anthony Bordain.
Just two weeks ago, Cyrell opened up about bullying in reference to her co-star and nemesis Martha Kalifatidis, who threw a glass of red wine over her head on the show.
She critiqued Martha's choice of becoming an anti-bullying activist, after Martha was seen to be a ring leader in a group of bullies on the popular reality TV show.
The MAFS star did not hold back against Martha, who along with Ines Basic and Jessika would often cause a multitude of drama during the dinner party.
After one social media user asked if the Channel 9 reality star has spoken with her fellow reality TV contestant, Cyrell said: "No I don't talk to Martha, I don't talk to snakes. I know she called Jules a snake but we all know who the bigger snake is."
Cyrell capped off her rant by taking aim at Martha's recent birthday splurge; hiring a Lamborghini for a day.
"Take responsibility for your actions, and you know you're as fake as that Lamborghini you hired."
Meanwhile, the Daily Mail has claimed that Cyrell and her boyfriend Eden Dally, 26, of Love Island Australia fame, have recently moved in together following a whirlwind romance.
In recent months, she has been spotted almost daily at Eden's $2.9 million mansion on Sydney Harbour in Drummoyne.
The four-bedroom house boasts panoramic harbour views, two floors, a wraparound courtyard, sunny lawn and large swimming pool, which Eden regularly uses for Instagram photoshoots.
