Cake (2015)

This movie is grim, but with good perspective on it's subject matter.  We have death of a child, debilitating chronic pain, opiate addiction, suicide, depression, divorce, a motherless child and two devastated fathers.  Jennifer Aniston, best known for her comic work, looks uncharacteristically awful.  Her hair is only washed once in the whole film, she is always wearing what she slept in, and she is disfigured by the terrible car accident that left her extremely damaged, both physically and emotionally.
Why, you should be asking at this point, watch this movie?  Well, the grittiness is very real.  When bad things happen, at least some people fall completely apart.  Her character is propped up by a long suffering housekeeper, but her hand up to starting the long arduous road to getting better is from the husband of a woman in her chronic pain group who committed suicide.  He, equally damaged as he is, is also just as angry as she is, and he tolerates her.  She needs that and so does he, and they give each other a bit of needed human companionship.  The leg up that she needs to crawl out.  It ends realistically.
