Sharon Osbourne was "very frightened" when she was suffering a mental breakdown.

She said: "I had given up. I just couldn't deal. At a very low point in my life, I was very frightened about what was going on with me mentally and the thoughts that were going into my head constantly.

"These thoughts coming into my head and pictures and people's faces and I couldn't control my head, but I couldn't verbalise it.

"I just didn't have the strength to even say I need help, help me because I just couldn't talk I was just flat, gone."

While Sharon's son Jack was the one to find her the right treatment, the 'Talk' star credits her husband Ozzy for being the one who persuaded her to seek help.

She told 'Access Hollywood': "It was actually Ozzy that got me to the hospital."

After Sharon's hospitalisation, she and Ozzy briefly split following revelations the Black Sabbath rocker had been unfaithful to her, but they have got their relationship back on track and they can't imagine life without one another.

Sharon said: "I can't imagine my life without him, and he can't imagine his life without me, and everything that goes in between.

"I don't know what else could happen in our lives that can try and separate us but things happen and we come right back together again."

And when it comes to her mental health, Sharon - who has Jack, 30, and daughters Aimee, 33, and Kelly, 31, with her 67-year-old spouse - is taking things one day at a time.

She said: "I think if you are born with [depression] you have it all your life, and it's an ongoing battle, so it's an ongoing thing of realising how blessed you are and what you got to be happy about in the day and I have so much."
