Williams, 63, was admittedly struggling with deep depression all the while battling his addictions, but the fight against the disease was something new and something he hadn't yet shared with the public.
"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," Schneider said in a statement.
"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."
Williams was found in his Tiburon, Calif. home on the morning of Aug. 11 by his personal assistant “in a clothed, seated position . . . slightly suspended” with a “belt around his neck," the Sheriff's Office confirmed, revealing that there were also "several acute superficial transverse cuts" on his left wrist.
"Robin spent so much of his life helping others. Whether he was entertaining millions on stage, film or television, our troops on the frontlines, or comforting a sick child — Robin wanted us to laugh and to feel less afraid," Schneider continued.
"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. His greatest legacy, besides his three children, is the joy and happiness he offered to others, particularly to those fighting personal battles."
