Former wrestler Daffney Unger -- who starred in the WCW from 1999 to 2001 -- has died after posting a very disturbing video to her social media page, TMZ Sports has confirmed.
She was 46 years old.
A spokesperson for the Gwinnett County Medical Examiner's Office confirmed the death to TMZ Sports, but did not reveal a cause or manner.
Daffney's friend, wrestler Lexie Fyfe, said the former WCW star -- real name Shannon Spruill -- was found dead Thursday morning.
"We are very sad to have to announce the passing of Shannon Spruill aka Daffney Unger," said Lexie, who told us she and Daffney were so close, they "called each other sisters."
"We are posting this at the request of her family. Please respect their privacy at this trying time. I will miss you my logical sister from another mister."
Daffney had gone on Instagram Live late Wednesday night and appeared to be in a suicidal state, saying in her video, "Do you guys not understand that I am all alone? Do you not understand that?"
She later could be heard in the footage saying, "Remember, my brain goes to Boston."
Fyfe tells us Daffney had been battling mental health issues in recent weeks ... and urged anyone who's going through similar struggles to reach out for help.
Fyfe also tells us cops initially had trouble finding Daffney following the posting of the video ... explaining Daffney had just moved into a different apartment just four days ago.
The wrestling world was rocked by the news ... with legend Mick Foley saying, "I'm so very sorry to learn of Daffney's passing. A terrible loss for her family, friends and wrestling. She was far ahead if her time in our business. #RIPDaffney."
Added wrestling star Frankie Kazarian, "RIP Daffney. Just, awful news. She was a guest at my wedding…This is so incredibly sad. Please, reach out. Always. Godspeed."
After her stint in the WCW, Daffney went on to have a big role with Total Nonstop Action Wrestling from '08-'11. She retired a short time later.
