Woman dies of illness and sells her eye

Only remember one scene: a woman was dying of an incurable disease, most likely lungs' cancer, and knowing that she had no more than a few months left, she sold her eye. Thus, she, dying, helped her children financially.
Movie probably 2010-2015.

Never Let Me Go (2010)??

It's definitely not the right movie because I haven't watched it.
However, you yourself do not know if there is that episode.

Ok.
