Animal rescue activist and YouTube star Mikayla Raines has died by suicide, according to her husband. She was 29.
Ethan Raines announced her death in an emotional video he posted to her YouTube channel on Monday.
He said that for years his wife suffered from various mental health issues and struggled to cope with online criticism.
"She couldn’t bear what she was feeling any longer, and she ended her life," he said. "And it breaks my heart that someone who is selfless and devoted her life to animals could have so much negativity pointed at her."
"And 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 you had to feel what she felt," he added. "I wish you had to feel what I feel."
Mikayla Raines created an animal rescue nonprofit, SaveAFox Rescue, in 2017, when she was just 20 years old. The organization, which is based in Lakeville, Minnesota, is dedicated to rescuing foxes from fur farms and providing them with "forever homes." The nonprofit has saved more than 150 foxes, according to its website.
