Davinia Taylor has opened up about her bipolar depression, revealing her new regime which has seen her kick her moods in to touch to find happiness again.

The 40-year-old actress, used to spend most of her time partying with her pals including the likes of Kate Moss in London’s Primrose Hill but it took it’s toll on her health and lead to her fighting alcoholism as well as battling severe pre and post natal depression and bipolar disorder.

But Davinia has been sober for the last nine years thanks to a stint in rehab, meditation training and her new exercise regime.

In an interview with Closer magazine, she said: “The only thing I’ve got in my artillery is exercise!”

The mum of three – who has joint custody of son Grey, 10, as well as two boys with fiancee Matthew Leyden, Asa, four, and Jude, two and son Lux, aged six, whose father remains unnamed – is taking part in this Sunday’s Virgin Money London Marathon to raise funds for health charity Mind.

But exercising has changed her mindset completely. She says: “I don’t drink any more because I’m an alcoholic, and I don’t smoke. I’ve swapped the fashionista set for running clubs and sobriety. If someone had told me at 30 that I’d be running the London Marathon at 40, I’d have laughed. I can hit rock bottom pretty quickly; I need something pretty easy to get me out of it. Running is free and simple and it works – suddenly I’m a better person.”

Davinia admits pre and post natal depression “almost killed me”. She continues: “Depression touches anyone – rich or poor – if it wants you, it’ll have you.”

All Davinia’s hard work is paying off as she’s come off the medication. She adds: “I’m not on any medication at all now, but I was picked on loads for bi-polar and depression. They made me lethargic and numb. They don’t make you sad, but they don’t make you happy either. Running gives you that boost of endorphins – maybe I wasn’t born with enough or maybe I drank them away! But it’s working for me and I’m in a happy place.”
