The star revealed that she was 'days from death' and was told by a therapist that she 'might not make it.' Honest: The singer has been focusing on her fitness and documenting her progress on social media after a stint in rehab 'What I was doing was a suicide mission. I was crying out for help when I couldn't actually ask for help. When you're an addict, it feels like there's no way out' she told The Sun, just 36 hours after leaving rehab. At the end of last month, the mother-of-two candidly detailed her three-year drug and alcohol addiction which left her 'close to death'. Updating fans on how she's holding up, Michelle said: 'Just wanted to say that I feel so much better today than I did do last week. 'I visited my home Priory yesterday and got to see my therapist and some of the guys who I was in there with looking great, and they're leaving today some of them actually, and I wish them all the best if you're watching this.' The star then continued to thank her fans and that she feels like she's part of an 'exclusive club' since her rehab stint.

'The people who are reaching out to me, friends from past and present, you never know what somebody's going through and if you need help just reach out and ask for it. I feel blessed.'

Posting a sweet picture of herself kissing her son, seven, on the head, the singer penned: 'Today I've been low. Cried a lot, for no particular reason, heart heavy and sad, like I'm mourning a friend. But the friend wasn't a friend.. it was alcohol. 'Then just now this little man hugged me and told me he was proud of me and 'Don't cry mummy, it's all gonna be ok' then the mourning stopped. And my heart again filled with love and gratefulness..'
