Trish Stratus is mourning the loss of her mother, Alice Stratigeas ... with the WWE Hall of Famer announcing she passed away last week after a battle with cancer.
Stratus shared the tragic news with her fans in an Instagram post on Wednesday ... saying she hasn't been able to find the words until now -- and that writing it "makes it more real."
"She fought through so many battles in her life with a strength that amazed me, and even in her hardest days, she was still thinking of everyone else first," Stratus wrote.
