When Emma gave birth, the extreme lows of her pregnancy were replaced by an unexpected high. She felt amazing in the days after her baby was born - but she didn't sleep and her behaviour became increasingly erratic.
A few weeks later, her mood flipped again. When her baby was three weeks old, Emma took an overdose.
It took a week in hospital for her liver function to return. But even after that, she was in and out of hospital for a year before finally being diagnosed with bipolar disorder, and medicated correctly.
"If I had the correct care, and been listened to during my pregnancy or even earlier, I could have avoided taking that overdose - 100%," she says.
It wasn't Emma's first experience of poor mental health - she'd spent her teens seeing doctors and receiving different antidepressants. No one had ever suggested she might have bipolar disorder.
