Freak City (1999)

Today, people like them would be put in an assisted living situation or some other situation. The idea is always to strive for the most normalized environment-the environment closest to what other people experience everyday---even if they were on SSI or if money was an issue. There are actually few institutions like that left--those that are look very little like that hospital.

The fact that the main character was over 18 makes it even harder to believe because if she did not want to live there then there is no way they could make her stay.
