Her post in full read:
For a lot of people, being arrested for common assault is an extreme way to have some sort of spiritual awakening but for me it's become the normal. I've been pressing the snooze button on many stresses in my life - for my whole life.
I've accepted shame and toxic opinions on my life for over 10 years and yet told myself it's all part of my job. No complaining.
The problem with brushing things under the carpet is .... they are still there and one day someone is going to lift that carpet up and all you are going to feel is shame and embarrassment.
On December the 12th 2019 I was arrested for common assault on my boyfriend ...
Within 24 hours my whole world and future was swept from under my feet and all the walls that I had taken so long to build around me, collapsed.
I am suddenly on a different kind of stage and everyone is watching it happen. I have always taken responsibility for what happened that night. Even on the night. But the truth is .... It was an accident.
I've been having some sort of emotional breakdown for a very long time.
But I am NOT a domestic abuser.
We had an argument and an accident happened. An accident.
The blood that someone SOLD to a newspaper was MY blood and that was something very sad and very personal. The reason I am talking today is because my family can't take anymore.
I've lost my job. My home. My ability to speak. And the truth has been taken out of my hands and used as entertainment. I can't spend every day hidden away being told not to say or speak to anyone.
I'm so sorry to my family for what I have brought upon them and for what my friends have had to go through. I'm not thinking about 'how I'm going to get my career back.'
I'm thinking about how I'm going to get mine and my family's life back. I can't say anymore than that."
It comes after the last photo of the Love Island host was shared - taken just hours before she died by suicide at her London home on Saturday.
The 40-year-old TV star was dressed in red as she celebrated Valentine's Day with friends.
Her friend Mollie Grosberg, a TV producer, shared the snap on her Instagram with the caption: "Our funny valentine bought us cookies and oat milk this year."
Grosberg added that she is looking after Flack's beloved dog, Ruby.
On Saturday, Flack's family released a statement confirming the devastating news.
"We can confirm that our Caroline passed away today on the 15th February," it read.
"We would ask that the press both respect the privacy of the family at this difficult time."
ITV - the network responsible for creating the dating reality-TV show - says everyone at the network is shocked.
"Everybody at Love Island and ITV is shocked and saddened by this desperately sad news.
"Caroline was a much loved member of the Love Island team and our sincere thoughts and condolences are with her family and friends."
Meanwhile Caroline's manager Francis Ridley has also paid tribute to the much loved star.
He revealed: "We are devastated at the loss of our client and friend Caroline Flack.
“An immensely talented young woman who was at the top of her game professionally and loved by television viewers across the country.
“Our thoughts are with Caroline’s family at this time.”
The 40-year-old was due to face court next month on charges of assaulting her boyfriend, Lewis Burton.
The former Love Island presenter's last Instagram post showed her giving her pet dog Ruby a kiss.
