The practice of self-injury is considered deviant and pathological, and the stereotype of a self-injuring individual is a young, white, middle-class woman. By using an autoethnographic approach, I elucidate how four women and I, aged 35–51, with experiences of self-injury in adulthood, use, internalize, and speak through dominant discourses of self-injury. The practice of self-injury is an embodied one, and self-injury is stereotypically associated with immature, irresponsible, and emotionally unstable young women. As adult women who self-injure, we use and speak through this representation, which, to some extent, affects our self-image and identity as we are often “misrecognized” as full partners in everyday social interaction or when we represent our professions. Still, we resist the idea of self-injury as stemming from immaturity, and we work to reclaim our bodies and agency from the medicalized, ageist assumptions of the practice of self-injury. By doing this, we can also rewrite and transform the meaning of this practice. Our self-inflicted wounds or scars do not define who we are nor our level of maturity, intelligence, and attractiveness. Thus, we acknowledge that we have the right to our own bodies and what we do to that body.
