'A Letter to my Body' is a series of essays in which five thinkers, artists and writers ask themselves how they relate to their own bodies.
In this first essay Sarah Graham, who is now a successful therapist and addictions counsellor, explores her at times turbulent relationship with her body.
From the age of eight Sarah was given ongoing medical treatment for a disorder of sexual development - but she only learned the real nature of her diagnosis at the age of twenty-five when a gynaecologist finally revealed the truth: that she is an intersex woman.
She has XY chromosomes.
She had never questioned her sex and had lived her life as a woman.
Doctors had even shielded her parents from the truth about her gender.
The shock of the revelation led Sarah on a path of depression and addiction which nearly killed her.
However she has gradually rebuilt her health and her self esteem.
In this essay she makes peace with her body and questions our society's polarised expectations of gender.
