Cherelle Griner Says Brittney At Rock Bottom In Russia, 'My Life Just Doesn't Matter'

Brittney Griner's wife says the WNBA star has hit the lowest moment of her life while locked up in Russia ... saying the basketball player has told her, "I feel like my life just doesn't matter."

Cherelle Griner nearly came to tears while discussing the state of her wife with Gayle King this week ... explaining she's never seen Brittney reach such a dark place before.

"BG's at her absolute weakest moment in life right now," Cherelle said. "She's very afraid about being left and forgotten in Russia. Or just completely used to the point of her detriment."

Brittney was arrested in February after she was accused of bringing hashish oil in her luggage to a Moscow airport. She later fessed up to the crime, and was sentenced to nine years in prison over it all in August. She is appealing the ruling, though she's expected to lose that at a hearing later this month.

And, Cherelle said the last time they were able to speak on the phone, she sensed something was very wrong with her wife.

"It was the most disturbing phone call I had ever experienced," Cherelle said. "And I've known BG 11 years. So I'm like, that was the most disturbing conversation."

Cherelle said Brittney has told her things like, "My life just don't even matter no more," and, "Am I just nothing?"

Cherelle added that she's very worried Brittney could ultimately be moved to a labor camp following her appeal hearing on Oct. 25.

"My brain can't even fathom it," she said.
