According to his official autopsy report Don Cornelius had been experiencing seizures and was in extreme pain before committing suicide earlier this year...
Don Cornelius was in an extreme amount of pain in the days before his death and minutes before he shot himself, Don phoned his son and told him, "I don't know how long I can take this" ... this according to the autopsy report obtained by TMZ.
According to the report, the "Soul Train" legend had been experiencing seizures as a result of an aneurysm he suffered 15 years ago.
But Don's health took a dramatic turn for the worse in the last 6 months of his life ... and he became "very depressed about his failing health."
Don called his son at 3:00 AM on February 1 ... and warned his son, "I don't know how long I can take this." Don's son told him he'd rush right over ... and Don said he'd leave the back door open.
When Don's son arrived to Cornelius' Los Angeles home, he detected an odor of smoke and saw Don seated in a chair with a pistol in his right hand.
