Weight and body image have been rather tough subjects for Demi Lovato over the years. According to

, Demi recently reminded the public during her PSA for the Mental Health Listening and Engagement Tour that we should all rethink the way we view eating disorders such as bulimia and anorexia.

, Demi Lovato admits to struggling with her eating disorder on a daily basis, and even admits to almost returning to rehab to address the matter.

“It’s been difficult. I almost went back to rehab for my eating disorder last summer. I was obsessing over food and terrified of it at the same time,” said Demi during an interview with
