Ozzy Osbourne Opens Up About Mental Health: 'My Brain Is Crazy'

Ozzy Osbourne has been "heavy training" his body to get ready for his final performance both with Black Sabbath and as a solo artist this summer, but on a new episode of his radio show the Prince of Darkness admitted he's also been dealing with some mental setbacks.

“I’ve got this trainer guy who helps people get back to normal,” the singer explained about getting in shape physically. “It’s hard going, but he’s convinced that he can pull it off for me. I’m giving it everything I’ve got.”

Osbourne’s co-host Billy Morrison then asked if he had been “waking up thinking about [the concert], stressing about it.”

“Sometimes, but what if I start obsessing all the time? I’ll be insane by Friday, you know?" Ozzy said. "So, I’m just taking it one day at a time."

"My head’s crazy. ADHD – I have that badly,” he confessed. “I will have done the show and died a death before I even started my exercises. So I try and put it on the back burner. I’m not going up there saying, ‘It’s going to be great. I’m really confident.’ In my head I will have died on my a**.”

“All I can say is I’m giving 120er cent," Ozzy concluded. "If my God wants me to do the show, I’ll do it.”

The final show is being billed as "Back To The Beginning" and is to take place July 5 in Birmingham, UK. The all-day event will also feature sets from Metallica, Slayer, Pantera, Alice in Chains, TOOL, the surviving members of Soundgarden and many other rock and metal icons.
