Mel B also opens up about her suicide attempt, which came during a run of live shows, and says she downed aspirin pills.
The Spice Girls singer has recalled how she felt "emotionally battered" when she made a suicide attempt in 2014 in a bid to escape her marriage to then-husband Stephen Belafonte, who she feared would attempt to "ruin" her career and "destroy" her family.
In her new book, the Spice Girl reveals that despite earning more than £80million during her career, she was left with nothing after the split.
"On so many levels I felt myself sinking", she writes. Of all the memories from all those hours, it is the one that still floors me.
In August this year Mel revealed she was seeking treatment in a British facility after being diagnosed with Post-Traumatic Stress Disorder (PTSD).
She went on to say that she knew she had to get the pills out of her stomach before it was too late but the door in her room was jammed.

She said: "I had surgery on my boobs and there were complications, but I didn't have them corrected". "Tell me. I know you have been snorting that s**t!' he'd yell".
"It was the saddest moment of my life", Brown admitted.
She was later taken to hospital, and despite being covered in bruises and suffering liver and kidney damage from her attempted overdose, she wanted to take her place on the judges' panel for the live final of The X Factor. I asked for my hair to be pulled right back from my face. I'd never felt so in love.
"He could see me". While it was hard to tell at the time, due to the extensive body makeup she was wearing, Mel wrote she had bruises round her eyes, her cheek was swollen, and she had dark welts on her arms from the IV drips she was being administered in a High Dependency area of the hospital. "Untouchable. Melanie Brown. Wonder Woman", she wrote, adding that there was "no going back" from her message to Stephen. When I left him I walked away with nothing but $936 (£800) in a bank account and suitcases full of clothes, books and toys. With the help of Audible, Mel auditioned three different women for the gig, giving them juicy tidbits from her book to read aloud, like when her relationship with Eddie Murphy started to go "spectacularly wrong".
