Evanna Lynch, aged 11, battled Anorexia for 2+ years until she managed to gather the courage to write to her author-hero JK Rowling. The Irish actress, Evanna, wrote to Rowling to thank her for the magical wizarding world of Harry Potter that she could escape to; the books gave her "hope".
Writing back "like a councellor" Rowling encouraged Evanna, through multiple letters to overcome her eating disorder with bravery and then to strive for the role of Luna Lovegood; the role Evanna is now famous for creating. Miss Lynch is noted to have looked up to Luna throughout reading the novels thus amplifying the significance if her finally landing the role.
"Anorexia is destructive, not creative. The brave thing to do was not to succumb to it..." Lynch recalls from the resonating advice given by Joanna "Jo" Rowling.
Evanna is now a survivor of Anorexia and has not returned to her disorder, she's pursuing her acting career and also working with the Harry Potter Alliance Charity where she gets to write and talk to young girls about body issues.
