Robin Williams was sober, but was struggling with depression, anxiety and the early stages of Parkinson's disease when he died, his wife said Thursday.
Williams was found dead in his Northern California home Monday from what investigators suspect was a suicide by hanging.
While fans and friends have looked for answers to why the 63-year-old comedy icon would take his own life, his wife, Susan Schneider, issued a written statement that could shed some light.
"Since his passing, all of us who loved Robin have found some solace in the tremendous outpouring of affection and admiration for him from the millions of people whose lives he touched," Schneider said. "His greatest legacy, besides his three children, is the joy and happiness he offered to others, particularly to those fighting personal battles."
"Robin's sobriety was intact and he was brave as he struggled with his own battles of depression, anxiety as well as early stages of Parkinson's disease, which he was not yet ready to share publicly."
"It is our hope in the wake of Robin's tragic passing, that others will find the strength to seek the care and support they need to treat whatever battles they are facing so they may feel less afraid."
