Emily Mitchell, a popular social media influencer, was expecting to give birth to her fifth child when she mysteriously passed away this week.

Mitchell, from Rhode Island, ran the Hidden Way Instagram account. Her family said she was eating breakfast on when she suddenly “became unresponsive.”

Efforts to save her and her fetus were unsuccessful. Doctors have not yet determined a cause of death.

“Our hearts are broken and her joyful presence will be greatly missed by so many,” a message on a GoFundMe page for Mitchell’s family said. “Em made a big impact in so many people’s lives, and this loss is incomprehensible for anyone who knew her. Our friend was a dedicated mom and wife, she had a heart for the Lord, and loved her children so dearly.”

Mitchell and her husband, Joseph, shared the news of her most recent pregnancy with her 109,000 followers in November. On Dec. 8, she told her followers that she would be undergoing her fifth Caesarean section.

Her social media account showed her and her husband raising their 4 children, Finn, Isla, Eden, and Luna.

“Beautiful inside and out, Emily had an infectious smile and a kind, compassionate spirit,” her online obituary read. “Her exuberant personality radiated outwardly in her interactions and relationships with all who knew her. Emily was a symbol of strength during the most challenging of times for so many.”
