This movie is about the emotion, the experience and the very dangerous feeling hopelessness.
Its not about her past, it's not about "finding out" what caused her depression.
Depression is an illness that your lucky to recover from, most deal with it for their entire life, its always in the background.
This movie did an amazing job describing what depression feels like. If you've ever really been depressed this movie will bring those feelings out and put them on display.
This movie is not for entertainment, it's informational and raw. Perspective changing, and an empaths worst nightmare (in a good way),
5 out of 5, I recommend this movie to everyone, but watch it without a grain of salt, watch it for the experience and allow yourself to feel.
Any reviewer that has anything bad to say about it didn't watch it for the right reason.
SPOILER BELOW.....
Not all movies have to have a happy ending.
