In the statement, Flack described having a mixture of complex emotions and feeling like her "whole world" had been swept from under her feet.
"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," she said.
"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."
The statement then went on to describe her version of the alleged assault on Mr Burton and the media scrutiny that followed.
"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."
Mental health charities and psychologists say suicide is often due to a range of factors, rather than one specific thing.
The former host of the hit Love Island dating show had denied the charges, and Mr Burton also did not support the trial.
But Britain's Crown Prosecution Service (CPS) had chosen to press ahead with the case, prompting savage criticism from Flack's management team.
"The CPS should look at themselves today and how they pursued a show trial that was not only without merit but not in the public interest. And ultimately resulted in significant distress to Caroline," it said in a statement.

At the end of her post, Flack explained that she wanted to speak up because her family couldn'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," she said.
"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.
