Los Angeles radio station KKBT-FM's K-Sly, who appeared in the "I Like That" video and is close to Houston's camp, said the singer had been under psychiatric care last year for manic depression. Another source corroborated that claim, adding that Houston had also struggled with PCP.
"I was told he wanted to commit suicide and stabbed his eye out," K-Sly said. "He was telling people he was Jesus and wanted to go home to his Father."
I'd say that the PCP has got the best of him.
A manic person on PCP??
