The 63-year-old television personality discussed her future with the 67-year-old Black Sabbath rocker on Tuesday's episode of The Talk. Osbourne missed Monday's episode following word she and Ozzy have separated after 33 years of marriage.
"I have no idea what I am going to be doing for the rest of my life," the star admitted. "I don't know where I am going, who I'm going with and I just need time to think and really think about myself and what I really want for the rest of my life."
Osbourne thanked fans for their support, saying the outpouring of love has "empowered" her and given her an "inner strength." The television personality is avoiding media speculation, however, including rumors Ozzy was unfaithful.
"I've been avoiding looking at any pictures, reading anything," she said. "I know what's going on. I don't need to read about it and see about it because it's like putting salt on a wound. I don't need to."
The Talk host revealed she and Ozzy are speaking but said she "honestly" doesn't know if they will stay married. The rocker, who was reported missing in the wake of the split, is back in their home, while Osbourne has left their house for now.
"I am 63 years of age and I can't keep living like this," the star said before later adding, "I love Ozzy dearly. He's given me unbelievable life. He's given me three gorgeous children and I love him."
Osbourne and Ozzy married in 1982 and share 32-year-old daughter Aimee, 31-year-old daughter Kelly and 30-year-old son Jack. The Black Sabbath frontman, who was spotted in Los Angeles on Monday, assured fans he's still sober following news of the split.
"I have been sober for three and a quarter years," he said in a statement to E! News. "I have not touched drugs or alcohol in that time. Any reports that I am not sober are completely inaccurate."
