Pete Wentz
Pete Wentz, 28, is the bassist for Grammy-nominated pop punk band Fall Out Boy. "Sugar, We're Goin Down," a single off the band's 2005 album, "From Under the Cork Tree," went to No. 8 on the Billboard Hot 100 Chart, but the song's title parallels Wentz's battle with bipolar disorder.
"I have manic depression. I obsess over everything," Wentz told Britain's Q Magazine.
Wentz was diagnosed with bipolar disorder as a teenager. He also takes medication for anxiety and sleep.
In February 2005, Wentz passed out from an overdose of anxiety medications, although he denied that it was a suicide attempt.
"I was isolating myself further and further," Wentz told Rolling Stone Magazine. "And the more I isolated myself, the more isolated I'd feel. I wasn't sleeping. I just wanted my head to shut off, like, I just wanted to completely stop thinking about anything at all."
Wentz, who is in a relationship with pop singer Ashlee Simpson, seems to have his disorder under control, for the most part.
"When I am depressed, I can't get out of bed," Wentz said. "But right now, it's sunny and 65 in my head, so it's OK!"
