Still Alice ending explained (spoilers)

[Colindelia]

Alice continues to deteriorate from her Alzheimer's Disease, at a couple of points failing to recognize her children. Her suicide attempt by overdose (which she set up soon after her diagnosis) fails when she is interrupted and drops the pills. John moves away to take another job to support the family (and because he can't bear to see his wife get steadily worse), and Lydia moves back home to care for Alice. In the final scene, Lydia reads from 'Angels in America' and asks Alice what she took from it. Alice, now struggling to even form words, communicates that the passage was about love.
