This photo that Demi Lovato posted on Instagram is breaking our hearts.

On Sunday night, Demi shared the news that her beloved great-grandmother had passed away. An emotion-filled caption accompanied a sweet pic of Demi lying beside her “Mimaw.”

“This morning I lost my world and the world’s most special woman,” Demi writes. “I miss her more than words can even describe. There is an emptiness in my heart that only her spirit can fill and I pray that I will feel her by my side every single day until we meet again.”

Demi says that she never knew she could feel such a strong bond with someone 70 years her senior. “The pain I feel is almost unbearable but because of her strength I will power through it,” Demi continued. She seems to be taking some solace in the fact that Mimaw is now with Papa, her deceased husband of 53 years.

“I hate that I can’t hear your voice but I love that you are no longer in pain,” Demi’s touching post explained. “I love you so much and I miss you more than anyone could ever imagine. I’ll miss your smile, your wittiness, painting your nails and your kisses. I really do love you more. Rest in peace and most importantly rest in the Lord.”

Demi then posted a photo collage of Mimaw, herself, and some other family members, with a broken-heart emoji as the caption.

We hope Demi’s doing OK — there’s nothing sadder than losing someone you love.
