How does my thriller represent certain social groups?

The only Character in my thriller opening is a female character who is between the ages of 26 and 34 and is also from a middle class background. This is a typical character choice seeing as she is nothing out of the ordinary apart from her mental health issues. My character is also represented as a victim which is again typical for a female character and does not challenge any conventions, furthermore the audience is led to believe that they already know everything about her because of her social status. My character is also represented as mentally ill which may be seen as atypical however, it is thought that females are more likely to suffer from mental illnesses.
