This was very powerful but I think there should have been more background given and character development. I know some people view this as a selfish act but what many don't realize until they personally experience incurable illness themselves is that when one reaches a certain stage all those around them often become bitter and resentful of this person whom they view as taking up all their time, money, resources, etc. This is the ugly side of incurable illness that is left unsaid. There is nothing dignified about a long, lingering death in which everyone around you is worn out and tired of dealing with it. Nobody is happy at that point. Not the ill person, nor family or friends. The whole idea behind dying with dignity is to go out before that happens.
Maybe in this story they could have gone deeper into why she decided to do this and to illustrate that she didn't want to be a burden to her loved-ones and wanted to end it while people around her still had emotional and financial resources left, before her relationships started breaking down, while the people in her life still had empathy and were not too mired in their own feelings of anger, betrayal or abandonment; while there was still love between them.
I would have liked to have seen more about her other relationships other than just with her husband; how she and others in her life dealt with her incurable illness and reconciled with it.
This is a complex subject matter which I think should have been made a full-length movie in order to fully do justice to this topic.
