Inspirational speaker and YouTuber Claire Wineland, who had cystic fibrosis, died Sunday night. The 21-year-old activist had a successful lung transplant on August 26, but days later she suffered a severe stroke.
According to BBC:
In a post on its Facebook page, the Claire's Place Foundation said: "Our inspirational founder passed away. She was not in any pain and the medical staff said it was the most peaceful passing they had ever witnessed."
At a 2017 TEDx talk, Ms Wineland spoke about the importance of self-worth when living with a life-shortening illness.
"Life isn't just about being happy... It's about what you're making of your life and whether you can find a deep pride in who you are and what you've given," she said.
