**WARNING -- this tape is EXTREMELY emotional **
During the call, Teena's daughter tells the operator, "“I’m scared, I’m so scared! She’s lost her color…her color is gone."
Eventually, the operator realizes there is nothing she can do for the singer -- and instructs her daughter to wait outside for help.
As we previously reported, officials believe the 54-year-old singer died of natural causes -- possibly a massive seizure.
