Millie Bobby Brown is mourning the loss of her grandmother, who recently succumbed to her battle with Alzheimer's disease.

On Tuesday, Nov. 10, the Stranger Things star shared a post to Instagram, in which she detailed her grief. "There's no words that make sense right now. There's no feeling to pin point," she began her caption. "Loss is something so complex and I go thru spells where I cant stop crying and then I laugh about all the memories and then sit quiet and try to comprehend what happened."
