Coping with Bipolar Disorder

Just weeks before Garrett's death, Daphen says she noticed a change in Andrea's behavior. She says Andrea became very anxious over what would normally be simple decisions—and that Andrea admitted to hearing voices. "When you look back on the hindsight, [people are] like, 'Well didn't you think that was crazy or something?' Well I justified it," Daphen says.

Daphen—whose own child has been diagnosed with early onset bipolar disorder—says if you notice symptoms in a loved one, it is important to do the research and speak with doctors who specialize in the illness. "It's not just about medication," Daphen says. "You need to also get therapy because therapy comes with the medication."

Andrea's husband declined to appear on The Oprah Winfrey Show, and her daughter, now 21 years old, also turned down the invitation.
