Did Stephanie Buttermore Suffer From Any Ailments?
Buttermore didn’t openly share details regarding major health problems; however, she did possess a Ph.D. with a focus on ovarian cancer exploration. Furthermore, she temporarily stepped back from her social media engagement to prioritize her psychological well-being, revealing in May 2024 that she had been experiencing “debilitating” anxiety.
“My emotional state is the healthiest it has ever been, and I’d like to give some details. I no longer deal with anxiety. Not in the slightest,” Buttermore stated in her post at that time. “A few years prior, it was almost unbearable to the degree that I felt unable to breathe or even step outside. Now, I truly don’t need to be concerned whether people appreciate my posts or if they are making hurtful comments about me. Also, I no longer experience the highs and lows resulting from sporadic dopamine influxes each time I access the app. I am existing in a space free of judgment, and it is tranquil.”
