"Anxiety has always been present in the Seventh Art, you can find it in some of the exciting thrillers of Hitchcock as well as in several Hollywood comedies. And it is not strange since cinematography is inspired by reality, which gives us great doses of anxiety every day.
Luckily, there are some excellent films about anxiety that closely approach these disorders, so that allow us to better understand how the anxious mind works, in order to put ourselves in the place of people suffering from generalized anxiety, obsessive compulsive disorder, social phobia or post-traumatic stress disorder.
These psychological movies can also serve as a kind of antidote: when we understand the mechanism of these disorders, we can also notice the first symptoms of anxiety and stop them before it is too late." - Psychology-spot.com
