4.48 Psychosis sees the ultimate narrowing of Sarah Kane's focus in her work. The struggle of the self to remain intact has moved in her work from civil war, into the family, into the couple, into the individual, and finally into the theatre of phychosis: the mind itself. This play was written in 1999 shortly before the playwright took her own life at age 28. On the page, the piece looks like a poem. No characters are named, and even their number is unspecified. It could be a journey through one person's mind, or an interview between a doctor and his patient.
