… mentally unstable mother

Hello there! My wife and I are looking for the name of a horror movie where a ghost??/demon?? of mother’s dead friend from her childhood in an institution (orphanage or mental institution?), is haunting that now mentally-unstable mother (who takes pills) and is controlling her and telling her what to do. The daughter is being attacked or something in the hallway. Then, the daughter finds a photo of her mother, father and her friend (the ghost/demon girl) from the past. The ghost/demon girl reminds us of the demonic girl from the film; “Lights Out”. The ghost/demon girl doesn’t want to release the mother, as they were best friends in the past. Sorry for the poor description! I hope someone can help us. Thanks for reading!
