The world was shocked by the news last month that Russell had committed suicide. Was it the pressure of fame and the reality show cameras? Was it Russell's reported financial hardship, being thousands of dollars in debt? Was it a health issue? Now, Taylor reveals to our Nancy O'Dell that her husband did indeed have a family history of mental illness.
"Russell did have a family history of mental illness," says Taylor. "When he started taking medication, he made several comments to me that he didn't want to end up being one of those people that had a big bag of medication that was necessary to keep him stable."
Taylor says the medication did help stabilize Russell and helped calm his violent outbursts, but he reportedly stopped taking the medication shortly before he hanged himself.
