The 28-year-old actress says she only shared her story with others while researching for her new film "To the Bone", reported Femalefirst.
"When I went through my eating disorder, I never sought medical assistance. I created myths in my head about how I should get through things, so the idea that I could surround myself with truth and feel comfortable enough to speak mine allowed me to breathe.
"There's a scene in the film ('To the Bone') when we're in group therapy talking about the euphoria we experience - I'd never heard that weird enjoyment we feel from being in the disorder worded that way before - and in that moment, you caught Lily understanding it as opposed to just Ellen, my character," Collins says.
