I have watched a bunch of movies which I think are therapeutic for depersonalization disorder.

The therapy comes from actually projecting yourself into the picture. Then it gives you new boundaries and a release of emotions.

Stand By Me: I become Gordi. It gives me a role for what I missed.

Movies on kidnap (some Italian):

Ransom, with Mel Gibson and Brawley Nolte

Flight of the Innocent

I'm Not Scared

A movie about being a teen who can't talk:

Trapped in Silence

Movie about being physically abused by one's father

El Bola.
