Kelly Osbourne has shared a deeply personal message with fans after suffering a relapse in her sobriety.
The daughter of Sharon and Ozzy Osbourne spoke out to mark one year of being sober after relapsing during "one of the hardest years" of her life.
She said the "dark" period forced her to retreat from the spotlight and it was only thanks to the love and support of her family and friends she was able to pull through.
Kelly, 33, wrote on Instagram: "This past year has been one of the hardest years of my life and I feel it's time to share that with you guys.
"To cut a long story short things got really dark. I gave up on everything in my life but most of all I gave up on myself. Life on life's terms became too much for me to handle.

This past year has been one of the hardest years of my life and I feel it's time share that with you guys.
"The only way I knew how to function was to self medicate and go from project to project so I never had to focus on what was really going on with me. Something had to give... and it did.
"I have spent the past year truly working on my mind body and soul! I had to take a step out of the public eye away from work and give myself a chance to heal and figure out who the [bleep] I really am without a camera in my face."
Kelly went on to thank brother Jack, 32, for being her rock.
"I want to take this time to thank my brother @jackosbourne who answered the phone to me one year ago today and picked me up from where I had fallen yet again without judgement," she wrote.
"He has held my hand through out this whole process."
She also thanked Sharon and Ozzy "for never giving up on me" and said: "I love my family with all my heart."
Kelly concluded her post by saying: "Thank you to the friends who have walked the path of sobriety with me I could not have done this without their love and support. I can’t believe it’s been a year!!!
"I still don't know who the [bleep] I am or what the [bleep] I want but I can wholeheartedly confess that I'm finally at peace with myself and truly starting to understand what true happiness is. I'm sorry if I let anyone down it was just time for me to work on me! I love you guys!"
Kelly's always been vocal about her previous addiction struggles.
She started using prescription drugs as a teenager and told People magazine in 2009 she was taking "whatever I could sniff or swallow to not be me."
In 2004 she entered rehab and returned the following year and again in 2009.
Just two weeks ago, Kelly appeared on ITV's Loose Women where she said alcohol and drugs had been her biggest vices, but she "could be addicted to absolutely anything".
She said: "Relapse is one of the hardest things we face as an open addict who has been going through the programme and turned your life around."

"Rehab doesn't fix you. It just helps you to get yourself back on the right track. You're never fixed. You spend your life doing everything you can to never pick up and use again."
She added: "Every day I fight to stay clean and do whatever I have to do to be a better person because I'm so comfortable being numb. I never did drugs to party, I did drugs because I hate feeling and used to be incapable, even if it was happy and good things, I didn't think I deserved it."
