TERREL OWENS: I WAS NOT TRYING TO KILL MYSELF

Terrell Owens claims his assistant was WRONG when she told a 911 operator that he tried to commit suicide on Oct. 6 ... this according to a statement from his publicist.

T.O.'s rep, Diana Bianchini, tells TMZ ..."Terrell Owens absolutely did not attempt suicide nor did he attempt to overdose on pills on Oct. 6, 2011."

"The facts are that [T.O.'s assistant] arrived at his home that evening after he had already taken a sleeping aid to fall asleep. He was unresponsive because of this."
