An extreme close-up shot of the protagonist's eye would suggest to the audience that by watching the film they are looking into her soul and trying to figure out why she is psychologically unstable. An over-the-shoulder shot would allow the audience to see the film from the protagonist's perspective and make them more sympathetic towards her. A high angle close-up shot would be used to portray the protagonist feeling fragile after experiencing extreme trauma by making her appear smaller and weaker.
