People living with anorexia nervosa (AN) often report experiencing an inner voice that dominates their thinking and behaviour, and prevents them from progressing towards recovery. Little systematic investigation has been made of this entity. A qualitative study was conducted to explore people's experiences of living with an 'anorexic' voice. Data were collected in the form of written reflections produced by those with the condition. A thematic analysis, involving the two authors, was employed, and the computer programme Atlas-ti helped with data management. Poems, letters, and reflective narratives were provided by 21 females with AN. A key theme from these data was the toxic relationship participants described with their inner voice. This idea was explored by considering and comparing their writings with research investigating the perspectives of women enduring domestic violence; parallels between the two groups became clear during analysis. A novel way of considering AN outlined in the paper, as someone entrapped in a toxic relationship, has implications for practice and for further research.
