Beloved YouTube star and animal rights activist Mikayla Raines’ cause of death has been confirmed.

The 29-year-old, whose animal rescue efforts earned her a loyal social media following, died by suicide, the Midwest Medical Examiner’s Office said, confirming her husband Ethan Frankamp’s initial post.

Raines hanged herself in the barn on her property in Faribault, Minn., the medical examiner said. She was found dead on June 20, TMZ reported.

Her death was announced in a June 22 Instagram post by her distraught husband.

“She couldn’t bear what she was feeling any longer, and she ended her life,” he said, saying her death is “the biggest loss of my life.”

Frankamp said his late wife, who boasted more than 2.45 million YouTube subscribers, was the victim of an “online bullying campaign” from people she knew and those who worked at “other animal sanctuaries” over the years.

“[Mikayla] felt as if the entire world had turned against her,” Frankamp said, adding that this “hurt her a lot.”

Frankamp said he performed CPR on Mikayla for 15 minutes when he found her lifeless body while he waited for paramedics to arrive.

He added that her young daughter, Freya, was “heartbroken” by her mother’s death.

“To those of you that pushed her to this, every one of you that had been responsible for making her feel this way, I wish — I wish you had to see me find her, and I wish you had to watch me perform CPR on her for 15 minutes until the first responders arrived,” Frankamp said.

“We have suffered a loss that is unimaginable. Mikayla was truly the most amazing and inspiring individual I have ever known, and not having her here makes everything feel empty. I feel broken.”

“As many of you know she was on the autism spectrum and while that made her life very difficult, it allowed her to hyperfocus on one thing, and that one thing was obviously animals,” he added.

Following the news of her death, Frankamp said he “will do whatever I can” to continue the Save A Fox rescue center.
