'A dark disease': Inside Bindi Irwin's battle with crippling endometriosis as she announces she is 'pain free'

Wildlife warrior Bindi Irwin has shed more light on her crippling endometriosis battle

The 24-year-old, who recently underwent surgery for the condition, connected with a fellow endo sufferer who understood her experience of the "dark disease".

While celebrating being "pain free" from the chronic illness, Irwin finally met an American woman, Leslie Mosier, who helped her through the journey.

Their friendship was born out of trauma - however Mosier said in a gushing Instagram post she was grateful the young mum is such a passionate advocate for endometriosis patients.

"Endometriosis is a dark disease, but out of my journey came a bright light – my friendship with @bindisueirwin," Mosier wrote, sharing some photos of herself and Irwin.

"When I was going through the thick of it I couldn't possibly see how any good could come out of my pain. But the connection with another who shares the experience and understands you in a way that few can, is like none other."

Irwin and Mosier met in-person after the conservationist flew to the US for the annual Steve Irwin Gala dinner in Los Angeles.

Mosier also happily announced she and Irwin are now "pain free" in her social media message.

"We finally met in person and it wasn't only special to finally meet, but we were both PAIN FREE! It was surreal, a moment we both dreamt of," she continued.

"The endo community is beyond lucky to have Bindi as an advocate. And I feel so lucky that we were brought together. Now that we are both pain free we have so many happy adventures ahead."

Mosier also spent time with Robert and Terri Irwin during their visit to LA and posted a sweet tribute to the Irwin family.

"I don't have words for what this family means to me," she captioned a selfie of the Australia Zoo owners.

"They say don't meet your heroes, but they definitely weren't talking about the Irwins when they said that! Such a magical start to a beautiful friendship."

In a 15-minute-long video uploaded to Instagram this week, Irwin went into detail about her battle with endometriosis, which started when she was just 14 years old.

"I was really active kid and all of a sudden I was getting so tired so easily and was always in pain," she shared to her 5.4 million followers.

"We tried and tried and tried for years and years and years and then finally a doctor said to me, this is just part of being a woman. And that's when I gave up. I stopped looking for answers. I stopped trying to find help," she said in the video.

It wasn't until she had given birth to her daughter, Grace Warrior Irwin Powell, now two years old, that she renewed her search for answers.

Irwin decided to get the surgery late last year when she was with her family in the US, with doctors finding 37 lesions and a chocolate cyst on her ovaries. Though recovery took a long time, she says she feels much better now.
