Brave Gail Porter is smiling again as she vows to turn her life around after 'suicide attempt' and rehab

Gail Porter was photographed looking happy and relaxed as she stepped out in London last week following a week-long stint in rehab for depression.

The 40-year-old star, who is alleged to have attempted to commit suicide seven weeks ago, went for a casual look in a black vest top and jeans, teamed with huge sunglasses as she chatted on her mobile phone and enjoyed the sunshine.

And friends of the presenter's have said Gail is working hard to turn her life around after apparently being detained under the Mental Health Act and sent to rehab.

Brave: Gail Porter was seen in London last week looking happy and relaxed after vowing to turn her life around following her alleged suicide attempt

A source told Closer magazine: 'Gail is determined to be strong and turn her life around for her eight-year-old daughter Honey.

'Gail has battled depression, anorexia, self-harming and hair-loss condition alopecia for years, but now she wants to focus on all the positive aspects in her life and be the best mum she can be. 

'She wants to draw a line under the past and start again with a clean slate. Her friends still worry about Gail's health but they are giving her as much support as possible.'

And despite the fact that Gail's boyfriend of two years, 25-year-old Jonny Davies, has apparently moved out of the house they shared, he has been working hard to nurse her back to health.

The source added: 'Gail and Jonny have had an on/off relationship, but she needs him more than ever. He's been helping her settle back into normal life.'

Porter has spoken openly about her mental issues, which have affected her throughout her adult life.

Following the birth of her daughter in 2003, Porter was diagnosed with post-natal depression. In addition, she was also diagnosed as being bi-polar in 2005.

Back on track: Gail is hoping now to get back to normality

Also in 2005 she had to have stomach pumped after overdosing on pills following the breakdown of her marriage to Honey's father, Toploader guitarist Dan Hipgrave.

At the time, she insisted it was a 'cry for help', not a genuine suicide attempt, and blamed taking herself off Prozac too quickly, saying: 'I didn't want to die. It was just a real cry for help, I felt so alone.'

She has also admitted to self-harming when she's feeling stressed, saying: 'I really needed to hurt myself. It was a sort of punishment.'

Gail added: 'When I felt overwhelmed, confused, more messed-up than usual, in my lowest moods I'd reach for the blade again.

'And again I'd have that strange reaction of relief and pain, always with a kind of self-loathing that seems to feed on itself.'

Now Gail is working hard to get back to normality and is hoping to return to work in the near future.

The source said: 'Gail is being so brave. She's such a bubbly and caring person, everyone just wants her to get better and back to work.'
