To the Unknown God (2019)

Lucia and her 17-year-old son Gabriel only have each other. The father left the family when Gabriel's older sister Anna died of leukemia eight years ago. Now Lucia works in a hospice, where she befriends retired professor Redetti and other palliative care patients, who know nothing of Lucia's personal tragedy. Over time, they help her understand how to "live the unliveable."
