2013 Steven Soderbergh film Side Effects.
As always a trailer:
At the beginning this movie would seem to be a study of people suffering from an ailment that is prevalent in our society. It is about how overpowering that ailment can be, how others treat those afflicted, and how it is treated. If it were nothing more than that it would have been an interesting film. This is more though, and while it wasn't bad it is definitely something we have seen many times before.
