Stephanie Buttermore’s last Instagram post
Buttermore was a successful fitness influencer, with more than a million subscribers (1.17 million) on YouTube and more than 500,000 followers on Instagram before stepping away from social media in 2024.
Live EventsIn her last post on Instagram in May 2024, Buttermore opened up about the changes she felt in her life after quitting social media and revealed that while she missed her fans, she chose to leave because her anxiety became “crippling… to the point I felt I couldn’t breathe or leave my house.” After a few months of being away from social media, she said her “mental health has been the best it’s ever been” and she was “way more present” in her life.
“My mental health has been the best it’s ever been, but I’ll give you some specifics. I no longer struggle with anxiety. At all. It was almost crippling a few years ago to the point I felt I couldn’t breathe or leave my house. Now I really don’t have to care whether people liked what I posted or if they are saying negative things about me. I also don’t have highs and lows from periodic dopamine hits every time I open the app. I’m living in a judgment free space and it’s peaceful here…,” she wrote in the caption of her last post.
YouTube channel, brand collaborations, and fitness-related programs were reportedly her primary sources of income.
